OPINION
Your mother refused to buy you a BB gun, warning that “you’ll shoot your eye out.” Apparently she was right to be concerned. Based on the facts of this case and a review of other cases on the topic, it seems that BBs are attracted to children’s eyes as politicians are attracted to television cameras. After losing the use of one eye, Aaron Swix together with his parents brought this products liability action against Daisy, the manufacturer of the air rifle which was used to shoot him, alleging that the air rifle was defectively designed. The district court dismissed Swix’s complaint. This appeal followed.
I
In May of 1999, Albert Carl Porrit purchased a Daisy Powerline 856 air rifle for his minor grandson, Nicholas Porritt. The air rifle was kept in a locked gun cabinet. On April 20, 2000, Nicholas, then age eleven, removed the loaded air rifle from the gun cabinet without permission. According to his affidavit, Nicholas took the safety lock off the gun and checked to see if the air rifle was empty. App. at 45. He then shook the rifle with the barrel facing down toward the floor. He pulled the bolt back and tilted the gun towards himself to see if there was a BB inside the rifle. He believed at this point that the rifle was empty. He subsequently pumped the rifle about five times and shot it at the floor. Only air came out. He then took the air rifle to the basement, pumping the rifle as he walked. When he got to the basement, he began to watch a movie and held the air rifle in his lap. Halfway through the movie, he picked up the air rifle, pointed it at his ten-year old friend Aaron Swix and “the air rifle went off.” Id. According to the plaintiffs, the result was painful and permanent injury to Aaron Swix and virtually complete loss of sight in his left eye.
On January 14, 2002, Aaron Swix and his parents filed a products liability suit against Daisy Manufacturing Company, in the Eastern District of Michigan, seeking *681 one million dollars and alleging claims of defective design and failure to warn of a known danger. In their amended complaint, the plaintiffs argued that “[t]he BB storage magazine in the model was dangerously and defectively designed [in that] ... it allowed a BB to become lodged in the forward portion, between the barrel and interior of the outer barrel assembly ... thus misleading the operator to believe ... the air rifle, to be completely empty of BBs, [even after pumping and firing], when, in fact, a BB would still be present in the magazine.” App. at. 8.
On March 14, 2002, Daisy filed a motion to dismiss the complaint arguing that a gun is a “simple tool” under Michigan law and the dangers of pointing it at another person are “open and obvious.” On April 18, 2002, plaintiffs filed a motion for partial summary judgment on the issue of Daisy’s liability but apparently they failed to file a timely memorandum in support. On August 14, 2002, the parties appeared at a telephonic hearing before Magistrate Judge Steven Pepe. At that hearing, Magistrate Judge Pepe granted the plaintiffs’ motion to amend their complaint to include the allegation that “[d]efendant’s primary marketing target (and principle [sic] consumers) was/were children and young adults” and that “[t]he model was particularly dangerous and defective when placed in the hands of minor children.” App. at 111, 113. The magistrate stated that “Defendant’s motion to dismiss will apply to the amended complaint.” App. at 113.
When the district court granted the defendant’s motion to dismiss one week later, on August 22, 2002, however, it gave no indication that it was aware of the recent amendment to the complaint. App. at 14-23. In oral argument, the parties agreed that Judge Woods may have been unaware of the amendment at the time he granted the motion to dismiss. In the same order, Judge Woods denied plaintiffs motion for partial summary judgment as moot. This appeal followed.

The parties do not dispute that Michigan state law applies in this diversity suit brought under 28 U.S.C. § 1332. The task of this Court, sitting in diversity, is to apply the same law as would be applied by Michigan state courts.
See Erie R.R. v. Tompkins,
The district court dismissed Swix’s complaint in this case finding that he had failed to establish that Daisy owed Swix a duty of care.- App. at 23. Under Michigan law, both a failure to warn claim and a defective design claim require a plaintiff to establish that the defendant owed him a duty of care.
See Davis v. McCourt,

A. Is the “simple tool” rule an absolute defense to a defective design claim?
The parties do seem to disagree, however, whether the fact that a product is deemed a “simple tool” and the danger is “open and obvious” is an absolute defense to a defective design claim or whether the obviousness of a danger is merely one factor in the analysis of whether the risks are unreasonable in light of the foreseeable injuries. We agree with virtually every Michigan court which has opined on the matter, all of which have suggested that the obviousness of a danger is merely one factor in the analysis of whether the risks are unreasonable in light of the foreseeable injuries.
See, e.g., Owens v. Allis-Chalmers Corp.,
In the design defect context, obvious risk may unreasonably breach the duty to adopt a design that safely and feasibly guards against foreseeable misuse. Because the manufacturer’s liability for choice of design is not determined solely by looking at the obvious nature of the *683 alleged defect, obviousness of the danger does not preclude the possibility that an alternative design could reduce the risk of harm at a cost and in a manner that maintains the product[’s] utility.
In the failure to warn context, the obvious nature of the simple product’s potential danger serves the core purpose of the claim, i.e., it functions as an inherent warning that the risk is present. Stated otherwise, if the risk is obvious from the characteristics of the product, the product itself telegraphs the precise warning that plaintiffs complain is lacking.
Id. (citations omitted). In other words, there is no need to warn of a danger where the danger is obvious, but in a design defect case, the court must also consider whether a manufacturer should have created the danger in the first place. For instance, the danger associated with a rag-doll with steak knives for arms (“Steak Knife Sally”) may be quite obvious, but it is equally clear that the risks associated with such a design choice far outweigh the utility.
Our opinion in
Kirk
is in accord.
See
Nonetheless, in deciding whether the simple tool rule applies to design defect cases, our discussion provided-insight into the question whether the open and obvious nature of a danger is merely one factor to be considered or is dispositive.
Id.
Specif-, ically, our opinion addressed whether
Fisher,
which was argued to have established the rule that the obviousness of a danger is dispositive, was overruled by
Prentis v. Yale Manufacturing Co.,
*684
Daisy argues that the “open and obvious” nature of a danger is dispositive based on
Mallard v. Hoffinger Industries Inc.,
Therefore, for the reasons discussed
supra,
we find that the fact that a
*685
product may be a “simple tool” is not dispositive in a design defect case-the obviousness of a danger is merely one factor in the analysis of whether the risks are unreasonable in light of the foreseeable injuries. The fact that a multi-factor analysis may be involved, however, will not prevent a defective design claim involving a simple tool from being decided as a matter of law where reasonable minds could not differ as to the outcome.
See Kirk,
In sum, whether the danger associated with a simple tool is “open and obvious” will determine whether a manufacturer owes a duty to warn and is also an important factor in deciding a design defect claim. This inquiry requires us to address two questions. First, is a Daisy air rifle a “simple tool” under Michigan law? Second, if so, is the danger alleged to be associated with a Daisy air rifle “open and obvious”?
B. Is an air rifle a “simple tool”?
Michigan caselaw does not provide a clear test for determining whether a product is a “simple tool.” However, the courts have categorized products as simple tools when one or both of the following conditions exist: (1) the products are not highly mechanized, thus allowing the users to maintain control over the products; (2) the intended use of the products does not place the users in obviously dangerous positions.
Davis,
C. Is the danger alleged here to be associated with a Daisy air rifle “open and obvious”?
The second question, whether the danger associated with a Daisy air rifle is
*686
“open and obvious,” is more difficult. In answering this question, “[t]he focus is the
typical user’s
perception and knowledge of whether the relevant condition or feature that creates the danger associated with use is fully apparent, widely known, commonly recognized, and anticipated by the
ordinary user or consumer.” Glittenberg,
In this case, Swix amended his complaint one week before the district court granted Daisy’s motion to dismiss to allege that “[d]efendant’s primary marketing target (and principle [sic] consumers) was/ were children and young adults.” App. at 111, 113. In essence, Swix has alleged that the typical or intended users of the Daisy air rifle are children. 4 We believe that the district court was unaware of this amendment at the time it granted the defendant’s motion to dismiss, which may explain its holding.
This allegation is crucial in that it distinguishes this case from every Michigan case which holds that the dangers associated with guns or other products intended for adults were “open and obvious.” These cases all applied an “objective reasonable adult standard,” not because it was an adult who was using the product which caused injury, but because the product in question was intended for and typically used by adults.
See Treadway,
If the typical user of a Daisy air rifle is a child, which we must presume to be true on a motion to dismiss, an objective reasonable child standard must apply.
See Kirk,
Therefore the question presented here is whether the reasonable child of whatever age the typical user of a Daisy air rifle is determined to be would know that it would be dangerous to aim the rifle at another and click the trigger, even after going through the process of emptying and testing the rifle that Porritt allegedly went through in this case. Given that this question has not yet been answered by any Michigan court and given that reasonable minds could differ as to the answer, we believe this question is not particularly appropriate for determination as a matter of law.

See, e.g., Glittenberg,
*688
Finally, though it might conceivably support a comparative negligence defense, the fact that Daisy intended that its air rifle be used under the direct supervision of an adult and that Swix’s grandfather had the same rule does not alter the “reasonable child standard” that applies in this case.
See Farm Bureau Ins. Group v. Phillips,
Moreover, a manufacturer has a duty to protect against foreseeable misuses.

Therefore, for the reasons discussed supra, we reverse the district court’s grant of defendant’s motion to dismiss and remand this case to the district court for further proceedings not inconsistent with this opinion.
Notes
. We note that there is a great deal of confusion in the language of many opinions, including Kirk, which have bearing on the question whether the simple tool rule is dispositive or *684 whether a reasonableness analysis applies. We believe that this confusion has been created, in part, because courts have conflated this question with the separate and potentially independent question of whether such cases can be decided as a matter of law. If each question is considered separately, however, it appears that there is not much disagreement. As will be discussed, it is clear that a reasonableness analysis applies but that the nature of this analysis will not prevent a design defect claim from being decided as a matter of law where reasonable minds could not disagree as to the outcome.
. Judge Kelly, in his concurrence in
Mallard,
supported the view that a “reasonableness” analysis should be applied in design defect cases involving simple tools.
See Mallard,

Mallard
argues that the court in
Glittenberg
could not be endorsing a reasonableness analysis in design defect cases, despite its clear language, because it expressly noted that its holding was not a departure from

. According to the affidavit of William F. Kitzes, Swix’s expert, a September 1975 study commissioned by Daisy found that the median age of purchasers of Daisy Power Line guns was twelve years old. App. at 91.
. Daisy also makes the argument that it had no duty to warn in this case as a matter of law, based on
Mallard,
in which the court mentioned that "if a child is capable of understanding a warning, the dangerous condition would be obvious to the child, rendering the warning unnecessary.”
