*530Penal Code section 245, subdivision (a)(1) (hereafter section 245(a)(1) ) prohibits "assault[ing] ... the person of another with a deadly weapon or instrument other *545than a firearm." In this case, the juvenile court found that defendant B.M.'s use of a knife with a dull tip and slightly serrated edge, which the court referred to as a "butter knife," violated section 245(a)(1). On appeal, B.M. argued that insufficient evidence supported the juvenile court's finding because she had not used the butter knife in a manner that was " 'capable of producing and likely to produce, death or great bodily injury.' " ( People v. Aguilar (1997)
We hold, consistent with settled principles, that for an object to qualify as a deadly weapon based on how it was used, the defendant must have used the object in a manner not only capable of producing but also likely to produce death or great bodily injury. The extent of any damage done to the object and the extent of any bodily injuries caused by the object are appropriate considerations in the fact-specific inquiry required by Penal Code section 245(a)(1). But speculation without record support as to how the object could have been used or what injury might have been inflicted if the object had been used differently is not appropriate. We conclude that the evidence here was insufficient to sustain a finding that the knife at issue was used as a deadly weapon, and we accordingly reverse the Court of Appeal's judgment.
I.
On the morning of July 2, 2016, seventeen-year-old defendant B.M. returned to her family's home after spending the night away. She was unable to unlock the front door with her key, so she began knocking on the door. When she received no response, she entered the house through a window.
*531Upon entering the home, B.M. went to the bedroom of Sophia, one of her sisters, and asked her why she had changed the locks. B.M. later acknowledged she was "mad" and "upset" when she confronted Sophia. B.M. yelled and threw a phone at Sophia and then went downstairs to the kitchen, where she grabbed a metal knife from the counter. B.M. testified she grabbed the knife because "it was just the heat of the moment, and [the knife was] just the first thing that caught [her] eye." The knife was about six inches long, with a three-inch blade that was not "sharp" and had "small ridges" on one side. Both B.M. and Sophia described the knife as a "butter knife."
B.M. returned to Sophia's bedroom with the knife. Sophia was clothed only in a towel because she had just gotten out of the shower when B.M. had arrived home. Sophia testified that when she saw B.M. with the knife, she covered herself with the blanket that was on the bed because she "didn't know what [B.M.] was going to do." She also testified that she "was pretty scared" because she **1183thought B.M. "could really ... hurt [her]." On the witness stand, B.M. was asked, "So did you use a motion like to stab her?" B.M. responded, "No, but as soon as I got close to her with the knife, she covered herself with the blanket."
B.M. approached Sophia, who was lying on top of the bed with her knees bent. Sophia testified that B.M. "came ... at [her] trying to stab [her]" and that from a distance of about three feet, B.M. made *546several "downward" "slicing" motions with the knife in the area around Sophia's legs. Sophia further testified that the knife hit her blanketed legs "a few" times and that the amount of pressure B.M. used was "maybe like a five or a six" on a scale from one to ten "if one is the least amount of pressure and ten is the most pressure." Sophia initially said B.M. poked her with the knife, but she later clarified that B.M. did not poke or stab her and that B.M. did not "hurt" her. B.M. testified she only "wanted to scare [Sophia]" and "had no intentions in actually stabbing [Sophia] with [the knife]."
B.M. then began arguing with her stepsister, who was also in the room. The argument eventually turned physical, and the fight moved from the bedroom to the downstairs of the house before spilling outside. During this altercation, Sophia called the police, who showed up and arrested B.M. A police officer later testified that B.M. told him "she [had] wanted to scare Sophia and admitted to making several [downward] stabbing motions at the bedding ... that Sophia had pulled up over her and the bed." A juvenile wardship petition was filed pursuant to Welfare and Institutions Code section 602, alleging that B.M.'s use of the butter knife against Sophia was an assault with a deadly weapon under Penal Code section 245(a)(1). (All undesignated statutory references are to the Penal Code.) The juvenile court sustained the petition. In concluding that B.M. had violated section 245(a)(1), the court *532noted that Sophia had testified that she "did feel the [downward] slicing motion on her legs" applied with a pressure of "a five or a six out of ten." The court also observed that even though the case involved " 'just a butter knife,' ... the circumstances of what happened here ... make it a felony."
B.M. appealed the juvenile court's order. As relevant here, the Court of Appeal rejected B.M.'s challenge to the sufficiency of the evidence supporting her adjudication under section 245(a)(1). The court reasoned that "[i]t matters not that [Sophia] was able to fend off great bodily injury with her blanket" or "that [B.M.] was not adept at using a knife" because B.M. "could have easily inflicted great bodily injury with this metal butter knife and just as easily [could] have committed mayhem upon the victim's face." The court concluded that the juvenile court's findings-"that the six-inch metal butter knife could be used to slice or stab, even though it was not designed for such," and that the knife was in fact "used in a manner 'capable' of producing great bodily injury"-were "not 'wholly irreconcilable' with the evidence."

"As used in section 245, subdivision (a)(1), a 'deadly weapon' is 'any object, instrument, or weapon which is used in such a manner as to be *533capable of producing and likely to produce, death or great bodily injury.' " ( Aguilar , supra , 16 Cal.4th at pp. 1028-1029,
A.
At the outset, we clarify several principles that guide our analysis. First, the object alleged to be a deadly weapon must be used in a manner that is not only "capable of producing" but also " 'likely to produce death or great bodily injury.' " ( Aguilar , supra , 16 Cal.4th at p. 1029,
The Attorney General argues that "capable of producing" and "likely to produce" are essentially the same because the term " 'likel[y]' " has the same meaning as " 'possib[le].' " But this construction is at odds with the ordinary meaning of "likely." (See Merriam-Webster Collegiate Dict. (11th ed. 2014) p. 721 [defining "likely" as "having a high probability of occurring or being true" and "very probable"]; Black's Law Dict. (10th ed. 2014) p. 1069 [defining "likely" as "probable"].) It is also inconsistent with how we have treated the term "likely to produce great bodily harm or death" elsewhere in the Penal Code. (See People v. Valdez (2002)
Our case law on the crime of assault is also instructive. Assault is a general intent crime; it does not require a *548specific intent to cause injury. (See *534People v. Williams (2001)
The Attorney General further contends that the Court of Appeal sufficiently addressed the "likely" standard by noting that " '[t]he use of an object in an assault increases the likelihood of great bodily injury.' " But the fact that B.M.'s use of the butter knife may have increased the likelihood of serious injury does not establish that her use of the object was likely to cause serious injury. An increase in likelihood from impossible to unlikely, for example, does not **1185show that the object was likely to cause serious harm. The use of an object in a manner "likely to produce" death or great bodily injury ( Aguilar , supra , 16 Cal.4th at p. 1029,
Second, the Aguilar standard does not permit conjecture as to how the object could have been used. Rather, the determination of whether an object is a deadly weapon under section 245(a)(1) must rest on evidence of how the defendant actually "used" the object. ( Aguilar , supra , 16 Cal.4th at p. 1029,
People v. Duke (1985)
*535Duke involved assault with force likely to cause great bodily injury ( § 245, subd. (a)(4) ) rather than assault with a deadly weapon. But we noted in Aguilar that "except in those cases involving an inherently dangerous weapon[,] the jury's decisionmaking process in an aggravated assault case ... is functionally identical regardless of whether ... the defendant employed a weapon alleged to be deadly as used or employed force likely to produce great bodily injury; in either instance, the decision turns on the nature of the force used." ( *549Aguilar , supra , 16 Cal.4th at p. 1035,
Although it is inappropriate to consider how the object could have been used as opposed to how it was actually used, it is appropriate in the deadly weapon inquiry to consider what harm could have resulted from the way the object was actually used. Analysis of whether the defendant's manner of using the object was likely to produce death or great bodily injury necessarily calls for an assessment of potential harm in light of the evidence. As noted, a mere possibility of serious injury is not enough. But the evidence may show that serious injury was likely, even if it did not come to pass.
Here, the Court of Appeal said B.M. could "easily have committed mayhem upon the victim's face." But the evidence showed that B.M. used the butter knife only in the area of Sophia's legs, which were covered with a blanket. There is no evidence that B.M. stabbed, sliced, or pointed the butter knife toward or near Sophia's face, or that B.M. attempted or threatened to do so. Nor is there evidence that B.M. was flailing her hand with the butter knife or otherwise wielding it wildly or uncontrollably. (Cf. People v. Simons (1996)
Third, although it is appropriate to consider the injury that could have resulted from the way the object was used, the extent of actual injury or lack of injury is also relevant. "[A] conviction for assault with a deadly weapon does not require proof of an injury or even physical contact" ( Brandon T. , supra , 191 Cal.App.4th at p. 1497,
B.
With these principles in mind, we turn to the case before us. Viewing the facts in the light most favorable to the judgment, we conclude that the juvenile court's finding that B.M. used the butter knife as a deadly weapon is not supported by substantial evidence, i.e., " 'evidence which is reasonable, credible, and of solid *550value.' " ( In re I.C. (2018)
Several circumstances support this conclusion. First, the record indicates that the six-inch metal knife B.M. used was "[t]he type of knife that you would use to butter a piece of toast"; it was not sharp and had slight ridges on one edge of the blade. (See Brandon T. , supra , 191 Cal.App.4th at pp. 1496-1498,
Second, B.M. used the knife only on Sophia's legs, which were covered with a blanket. There is no evidence that B.M. used or attempted to use the knife in the area of Sophia's head, face, or neck, or on any exposed part of her body. (See Beasley , supra , 105 Cal.App.4th at p. 1087,
Third, the moderate pressure that B.M. applied with the knife was insufficient to pierce the blanket, much less cause serious bodily injury to Sophia.
*537(See Brandon T. , supra , 191 Cal.App.4th at pp. 1496-1497,
The Court of Appeal, while acknowledging that "[t]he extent of the injuries, or lack of them, is relevant," suggested that Sophia was not injured in part because B.M. "was not adept at using a knife." This circumstance **1187"does not inure to [B.M.'s] benefit," the court reasoned, just as lack of injury is not probative in "the typical assault with a deadly weapon with a firearm when the defendant has poor aim." But the record contains no evidence as to how adept B.M. was in using a knife, and in any event, it does not matter what injury B.M. could have inflicted if she had used the knife in a more adept manner. (See supra , 241 Cal.Rptr.3d at pp. 548-549, 431 P.3d at pp. 1184-1185.) Such conjecture strays from the focus on the manner in which a defendant actually used the object, whether adept or not. Where a defendant uses a firearm with poor aim, lack of injury carries little weight not because it is appropriate to consider what injury could have resulted if the defendant had had better aim, but because in many circumstances using a firearm even with poor aim is likely to produce death or serious injury. (See, e.g., People v. Bradford (1976)
The Attorney General also echoes the Court of Appeal's reasoning that B.M. was willing to go to great lengths to injure Sophia because B.M. grabbed the knife only after she was unable to harm Sophia by "hurling" a phone at her and pulling her hair. But the record contains no facts regarding the phone itself or the manner in which B.M. threw the phone, and there is no allegation that B.M. used the phone in a manner likely to cause serious injury. Moreover, contrary to the timeline suggested by the Court of Appeal, the record indicates that B.M. pulled Sophia's hair during Sophia's phone call to 911, which occurred after B.M. used the knife against her. The inference that B.M. was intent on seriously injuring Sophia is belied by the absence of any evidence that B.M. attempted to use the knife again after using it on Sophia's blanket-covered legs. It is true that Sophia said she was "scared" that B.M. "could really hurt [her]" when B.M. showed up in her room with the knife. But Sophia's perception, considered with the totality of the evidence as to how B.M. actually used the knife, does not amount to reasonable evidence of solid value that B.M. used the knife in a manner likely to produce great bodily injury.
**1188The Attorney General further notes that "an object can be a deadly weapon even if there is no contact or injury, and ' "even if it's not actually used with deadly force." ' " But the cases he relies on involved a sharp object applied to a vulnerable part of the body ( D.T. , supra , 237 Cal.App.4th at pp. 697, 696,

Concurring Opinion by Justice Chin
CHIN, J.
I concur in the majority opinion, which I have signed. I do so with the understanding that we are not deciding the meaning of the word "likely" in the phrase " 'capable of producing and likely to produce, death or great bodily injury.' " ( People v. Aguilar (1997)
The majority opinion cites several definitions of the word "likely" according to which the word means " 'having a high probability,' " " 'very probable,' " or a " 'probability [that is] great.' " (Maj. opn., ante , 241 Cal.Rptr.3d at pp. 547-548, 431 P.3d at pp. 1184.) The opinion cites those definitions as examples that disprove the Attorney General's assertion that "likely" means "possible." (Id . at p. 547, 431 P.3d at p. 1184 .) The majority opinion should not be read as holding, based on those examples, that for purposes of Aguilar 's definition of what constitutes a deadly weapon, "likely" means "probable." Indeed, such a holding would be inconsistent with the majority's citations to In re D.T. (2015)
In this case, we do not decide the question of what "likely" means in the context of the Aguilar standard, and I do not wish to prejudge that question, but our resolution of the question calls for a careful analysis like the one that appears in People v. Superior Court (Ghilotti) (2002)
Turning to the facts of this case and mindful that we must construe the evidence in favor of the trial court's judgment, I agree with the majority that "[u]nder any plausible interpretation of the term 'likely,' the evidence was insufficient to establish that [defendant] B.M.'s use of a butter knife against her sister's blanketed legs was ' "likely to produce death or great bodily injury." ' ( Aguilar , supra , 16 Cal.4th at p. 1029,
Based on the foregoing understanding of the majority opinion, I concur.
