Plaintiff Robert Kirk appeals the summary judgment entered by the District Court for the Eastern District of Michigan in favor of Defendant Bic Corporation (Bic) in Kirk’s products liability suit. The district court certified this judgment pursuant to Fed.R.Civ.P. 54(b), we have jurisdiction, and the judgment is AFFIRMED.
I.
The facts in this case are not in dispute. On the morning of October 29, 1987, Diane Gryka returned home from work before her husband, Wayne Gryka, left for his job. Diane and Wayne smoked a pipe of marijuana together in their living room and, when Wayne had to leave, Diane fell asleep on the couch. They left their disposable butane fighter lying on the living room table.
While Diane slept, her five-year-old son used the fighter to light a candle. The boy then used the candle to set fire to the T-shirt worn by his three-year-old sister, Amanda, Diane awoke to her daughter’s screams but Amanda was severely burned before the flames could be extinguished.
Robert Kirk, as next friend of Amanda, filed suit in Michigan state court against Hanes Corporation (Hanes), the manufacturer of the T-shirt Amanda was wearing. Hanes removed the ease to federal court based upon the diversity of citizenship of the parties. Kirk then amended his complaint, adding Bic as a defendant and alleging that Bic had been negligent in failing to design a child-proof or child-resistant fighter.1

Rule 56 provides that summary judgment is appropriate whenever “there is no genuine issue as to any material fact and ... the moving party is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(c). The second summary judgment requirement involves, by its own terms, a determination of law. This determination we review de novo. Brooks v. American Broadcasting Co., 932 F.2d 495, 500 (6th Cir.1991). In the present case, the district court held, as a matter of law, that even though “injuries due to unsupervised children playing with the lighter may be foreseeable, such risks are not unreasonable.” Kirk v. Hanes, 771 F.Supp. 856, 859 (E.D.Mich.1991). Therefore, the district court concluded, Bic’s failure to “child-proof’ its lighters was not actionable under Michigan law. Id.2 We agree.
If the issue in this case is stated broadly, 1.e., whether a manufacturer of a simple tool is required to design safety features to protect users from dangers that are obvious and inherent in the tool’s utility, that question has been squarely addressed by the Michigan Supreme Court and resolved in favor of the manufacturer. See Fisher v. Johnson Milk Co., 383 Mich. 158, 174 N.W.2d 752, 753 (1970).
Even if the relevant issue is stated more narrowly (to avoid the controlling effect of Fisher), i.e., whether a manufacturer of a disposable lighter must child-proof its product, that question was addressed recently by a Michigan appellate court and, on the authority of Fisher, resolved in favor of the manufacturer. See Adams v. Perry Furniture Co., 198 Mich.App. 1, 497 N.W.2d 514, 520 (1993), application for lv. to app. filed, (No. 95875) (Feb. 9, 1993).
Kirk argues that Fisher should not control because it is out of step with recent Michigan Supreme Court decisions. Therefore, Kirk also argues that, because Adams’s reliance upon Fisher was error, Adams should be ignored. In support of his claims, Kirk cites Glittenberg v. Doughboy Recreational Industries, 441 Mich. 379, 491 N.W.2d 208, 214 (1992), and Owens v. Allis-Chalmers Corp., 414 Mich. 413, 326 N.W.2d 372, 377 (1982).
The task of this court, sitting in diversity, is to apply the same law as would be applied by the Michigan state courts. See Erie R.R. v. Tompkins, 304 U.S. 64, 78, 58 S.Ct. 817, 822, 82 L.Ed. 1188 (1938). Where a state’s highest court has spoken to an issue, we are bound by that decision unless we are convinced that the high court would overrule it if confronted with facts similar to those before us. Bernhardt v. Polygraphic Co. of Am.,, 350 U.S. 198, 205, 76 S.Ct. 273, 277, 100 L.Ed. 199 (1956). Moreover, where a state appellate court has resolved an issue to which the high court has not spoken, “we will normally treat [those] decisions ... as authoritative absent a strong showing that the state’s highest court would decide the issue differently.” Garrett v. Akron-Cleveland Auto Rental, Inc. (In re Akron-Cleveland Auto Rental, Inc.), 921 F.2d 659, 662 (6th Cir.1990) (emphasis added).
Because we are not convinced that Fisher would be overruled by the Michigan Supreme Court, or that Adams would be rejected by that court, we hold that these cases control and bar Kirk’s products liability claim based upon Bic’s allegedly defective design.
A.
In Fisher, as in the present case, the plaintiff claimed that the manufacturer of a simple tool was negligent for failing to design a safety device to protect him from an obvious danger associated with its use. Fisher, 174 N.W.2d at 753. The court observed that a “manufacturer • cannot manufacture a knife that will not cut or a hammer that will not mash a thumb or a stove that will not bum a finger.” Id. (quoting Jamieson v. Woodward & Lothrop, 247 F.2d 23, 26 (D.C.Cir.), cert. denied, 355 U.S. 855, 78 S.Ct. 84, 2 L.Ed.2d 63 (1957)). Therefore, the court held, manufacturers of such simple tools have “no duty *708to warn or protect against dangers obvious to all.” Id. (emphasis added).
Kirk contends that Fisher is no longer “good law” because Prentis v. Yale Mfg. Co., 421 Mich. 670, 365 N.W.2d 176 (1984), changed the standard for assessing manufacturers’ liability for negligent design. In Prentis, the court adopted a “pure negligence, risk-utility test.” Id. 365 N.W.2d at 186. Under this test, a product is “defective” and “unreasonably dangerous” if it poses an unreasonable risk of foreseeable injury. Id. at 187.
Even though Fisher was decided prior to Prentis, it also applied a “pure negligence” standard. There, the plaintiff sued the manufacturer of a wire, milk bottle carrier because, when the plaintiff dropped the carrier, the milk bottles broke and he cut his hand on one of the fragments. Although the court phrased its holding in terms of “duty, ” Fisher, 174 N.W.2d at 753, the holding clearly rests, in modem parlance, on the ground that the manufacturer did not breach its duty to market products free from unreasonable risk of foreseeable harm. While the risks that glass bottles "will break or that broken glass might injure someone are inarguably foreseeable, the court determined that such risks, as a matter of law, were not unreasonable given the obvious nature of the danger and the simple nature of the product. Id. at 753-54.
Our conclusion that Fisher remains viable and bars Kirk’s claim is consistent with the result recently reached, on nearly identical facts, by the Michigan Court of Appeals in Adams v. Perry Furniture Co., 497 N.W.2d 514 (Mich.Ct.App.1993). On the continued strength of Fisher, the court held that Bic’s failure to child-proof its lighters was not actionable under Michigan law. Id. at 520. The court reasoned that, although the risk that a child might injure himself with a lighter is foreseeable, such a risk is not unreasonable because the danger is obvious to adults who were the intended users of the product and who had been specifically warned to keep the lighter out of the hands of children. Id. Rather than hold Bic liable for the child’s injuries, the court held that “the risk of danger to children is best obviated by the supervisory control of the product by its adult purchasers.” Id. To hold otherwise, the court said, would be to make the manufacturer the insurer of its product, a position Michigan courts have consistently refused to take. Id.
B.
Kirk argues that Owens overruled Fisher and limited the “open and obvious danger” rule to cases based upon a failure to warn, rather than a design defect. We disagree. The court in Owens affirmed a directed verdict in favor of a forklift manufacturer on the ground that the plaintiff had not proven that the lack of driver restraints presented an unreasonable risk of harm. In reaching this conclusion, however, the court declined to hold that, simply because the lack of driver restraints was “open and obvious,” the forklift manufacturer could not be liable under Fisher. Owens, 326 N.W.2d at 376-77.
Owens, however, focused on the manufacturer’s alleged negligence in designing a forklift, a complex machine. Thus, it was a factually inappropriate case in which to apply the simple tool doctrine adopted in Fisher, a distinction which the court in Owens expressly acknowledged.
Our Court of Appeals has essentially limited language in our decision in Fisher by the fact that Fisher involved a simple product or tool. We believe that such a limitation is proper. Obvious risks may be unreasonable risks, and there is no justification for departing from general negligence ... principles merely because the dangers are patent.
Id. at 377 (emphasis added and citations omitted).
The last sentence quoted, upon which Kirk relies, must be read in light of the ratification of Fisher which precedes it. Obvious risks presented by one aspect of a complex machine, such as the forklift in Owens, may or may not be unreasonable when considered in the light of feasible alternatives, the utility of the product and the impact of proposed alternatives on its overall safety. This intricate balancing is, in the ordinary case, best left to the jury. Id. at 376-78. Those cases, as the above-quoted *709language makes clear, stand in contrast to eases such as Fisher in which the product is a simple tool that presents a single, obvious risk inherent in the product’s utility. Therefore, we read Owens as refusing to extend Fisher to design defect eases involving complex machines, while acknowledging the continued validity of Fisher in design defect eases arising out of the use of simple tools.3
Kirk also relies upon Glittenberg as support for his argument that Fisher should not be followed. Glittenberg concerned only the continued validity of the “open and obvious danger” rule in failure-to-warn cases, Glittenberg, 491 N.W.2d at 214-15, and its discussion of design defect cases is mere dicta. But, because even dicta may be of some value in ascertaining the relevant state law, we consider it on that basis. Bailey v. V & O Press Co., 770 F.2d 601, 604 (6th Cir.1985).
In Glittenberg, the court stated:
Our jurisprudence recognizes the well-established rule that there is no duty to warn of dangers that are open and obvious.[4] We have also narrowed application of the no-duty rule to those cases involving “simple tools or products.” Owens v. Allis-Chalmers Corp., 414 Mich. 413, 425, 326 N.W.2d 372 (1982). We have rejected the proposition that the “open and obvious danger” rule is an incantation that obviates the threshold inquiry of duty in design defect cases.
Glittenberg, 491 N.W.2d at 214 (footnote omitted).
We are not convinced that this language conflicts with our understanding that Fisher remains a viable theory of defense in design cases involving simple tools. The Glittenberg court’s citation to Owens as having limited the “open and obvious danger” rule, we believe, indicates that the limitation extends only to complex tools such as the forklift in Owens. Specifically, the second sentence in the quoted passage seems to us to support, rather than weaken, our conclusion that Fisher remains viable in design defect cases involving simple tools.
C.
Were we to reject Fisher and Adams, as Kirk argues, we would have to hold that the determination of whether a particular design presents an unreasonable risk of foreseeable injury may never be resolved by the court on summary judgment. This we cannot do.
Both Fisher and Adams were appellate reviews of summary judgments. Both decisions affirmed the use of this procedure where the facts were clear and no genuine dispute as to the reasonableness of the manufacturer’s conduct had been shown. Moreover, the Michigan Supreme Court has specifically condoned summary disposition of products liability suits in Moning v. Alfono, 400 Mich. 425, 254 N.W.2d 759 (1977). Despite the general rule favoring jury determination, the “issue of negligence may be removed from jury consideration if the court concludes that overriding considerations of public policy require that a particular view be adopted and applied in all cases.” Id. 254 N.W.2d at 770. We believe that this is such a case.
As with any manufacturer, Bic has a duty not to market products that present an unreasonable risk of foreseeable injury. We conclude, as did the court in Adams and the district court below, that no reasonable juror — in light of the fact that the danger of lighters is obvious to their intended users— could find that these lighters pose an unreasonable risk of harm. Therefore, the question of reasonableness, albeit a question of *710fact, is here appropriately resolved as a matter of law.5
III.
Not only is our conclusion that Fisher and Adams should control in this case compelled by Michigan case law, it is also compelled by common sense and the public policy of Michigan as articulated by that state’s highest court. In cases involving obvious dangers inherent in simple products, the Michigan Supreme Court has focused on where responsibility for the safe use of those products should lie. For Kirk to prevail, we must shift responsibility for safeguarding children away from the adult purchasers and intended users and on to the manufacturer. We believe that the Michigan Supreme Court would reject such a result on public policy grounds.
This case involves the allocation of responsibility between adults and manufacturers for protecting small children from the dangers inherent in everyday, simple tools that are manufactured for, and sold to, adult users. The Michigan Supreme Court addressed the policy behind this allocation in Moning. There, the court contrasted its case, in which liability was based upon a manufacturer marketing slingshots directly to children, with a hypothetical case, in which liability was sought simply on the basis that the use of slingshots entails an inherent danger of injury. Moning, 254 N.W.2d at 771. The court broadly hinted that this latter example, which we believe is equivalent to the present case, would be proper for summary disposition on the ground that the “interests of mature persons who wish to purchase and use slingshots might ... supersede the interests of those who may be harmed by their careless or improper use.” Id.
The court reasoned that summary disposition would be proper in its latter example because, if the product is marketed only to adults, as was the Bic lighter in the present case, the adults would bear responsibility for preventing careless use by children. Id. at 773. Having marketed its product directly to children, however, and thus bypassed adult supervision, the court held that the question of whether the manufacturer’s conduct constituted negligence must be resolved by a jury. Id. at 774-75.
Thus, Moning provides a clear statement of the public policy of the state of Michigan. A manufacturer who bypasses adults, upon whom the law ordinarily places responsibility, and markets a simple, but dangerous, tool directly to children may not avoid liability on the ground that the child “should have known better.” By the same token, however, where a manufacturer markets its simple tool only to adults, to whom the danger is obvious, and relies upon them to keep the product away from children, that reliance is, as a matter of law, not negligent. See Adams, 497 N.W.2d at 520.
IV.
In sum, we hold that the “open and obvious danger” rule, first enunciated in Fisher, remains a valid limitation on a manufacturer’s liability for claimed “design defects” in Michigan cases arising out of the use of simple tools. Therefore, on the continued strength of Fisher as evidenced by Adams, we hold as a matter of law that the risk of injury to this plaintiff, while foreseeable to Bic, was not unreasonable. The dan*711gers presented by a device whose whole purpose is producing flame are obvious. Where, as here, that device is sold only to adults who know and are warned of the dangers of letting children play with the product, Bic’s decision not to child-proof its lighters was not negligent.
The public policy of Michigan, as evidenced in Moning, provides that the primary responsibility for safeguarding children from the obvious and inherent dangers associated with the hundreds of simple tools with which we surround ourselves rests with the parents of these children and not the manufacturer of the simple tool.6 Only where the manufacturer has affirmatively bypassed this chain of responsibility should the child, as plaintiff in a lawsuit, look to the manufacturer for protection or compensation.
For the reasons stated above, the district court’s summary judgment in favor of Bie Corporation is
AFFIRMED.
. Kirk also alleged that Bic was negligent for failing to warn of the dangers of letting children have unsupervised access to its lighters. Kirk abandoned this claim, however, when discovery disclosed the fact that Bic did warn of this danger and when both of the Grykas admitted that they were well aware of the danger of letting their children play with lighters. Kirk v. Hanes, 771 F.Supp. 856, 859-60 (E.D.Mich.1991). We note, in passing, that Bic's warning, though given, is not required under Michigan law. See Glittenberg v. Doughboy Recreational Industries, 441 Mich. 379, 491 N.W.2d 208, 215 (1992).
. We note that the issue of Bic's liability under Michigan law for failure to child-proof its lighters has been before the Eastern District of Michigan three times in recent years. The results have run the gamut of possible outcomes: Bic not liable as a matter of law, Kirk, 771 F.Supp. at 859; Bic liable as a matter of law, Bondie v. Bic Corp., 739 F.Supp. 346, 349 (E.D.Mich.1990); and Bic's liability reserved for jury determination, Carlson v. Bic Corp., 840 F.Supp. 457 (E.D.Mich.1993).
. The persuasive force of Owens is further undercut by the fact that the argument rejected there was based upon the "open and obvious” absence of a safety device. In the present case, as in Fisher, the plaintiff's claim is barred by an obvious danger inherent in the use of the simple tool. While the absence of driver restraints in the forklift in Owens was certainly obvious, the need for those restraints was not so obvious. The danger that a forklift might roll over is less obvious than the danger that a flame might bum or that an unprotected glass bottle might break.
. The Glittenberg opinion cites Fisher for this proposition which, as previously discussed, held that a manufacturer has no duly to warn or protect against obvious dangers.
. This court reached a similar conclusion on nearly identical facts in Byler v. Scripto-Tokai Corp., Nos. 90-6112, 90-6113, 1991 WL 181749 (6th Cir. Sept. 7, 1991) (unpublished).
Were we to hold otherwise, the principle that we would have to adopt would permit virtually every manufacturer of a household tool or appliance to be found negligent. Knives, guns, blenders, saws, drills: the list of helpful tools perfectly safe in adult hands but dangerous in the hands of unsupervised children is endless. In all of these cases, the utility of the tool is high and the probability of harm is virtually nil when the child is properly supervised. Even here, had the adults not been drinking, had they not carelessly left lighters hanging around the house even though they knew that [the child] could operate a lighter and use it as a toy, the accident would never have happened. When the risk of harm is so low, and requires misbehavior on the part of supervising adults to occur, we cannot hold a manufacturer has acted unreasonably.
Id. at *6 (emphasis added). Although Byler applied Kentucky law, Kentucky and Michigan do not differ significantly on the issue of a manufacturer's negligence in design.
. It may be that this public policy has been superseded by recent changes in federal regulations, at least with regard to cigarette lighters. The Consumer Products Safety Commission recently promulgated regulations requiring that all disposable and novelty lighters meet minimum child-resistance standards beginning in July 1994. See Safety Standards for Cigarette Lighters, 58 Fed.Reg. 37,557-01 (July 13, 1993) (to be codified at 16 C.F.R. § 1210.1-1210.20). These regulations can be seen as an administrative finding that disposable fighters present an unreasonable risk unless equipped with child-resistant features. On the other hand, these regulations may merely represent the Commission's determination that, although ordinary fighters are not unreasonable, greater protection than that offered by the common law of products liability is needed. In any event, the regulations are irrelevant to Bic's liability in the present case as the findings were not made until after plaintiff’s injuries and the regulations do not become effective until July 1994.
