Window hammer

I bought this pair of window hammers/seatbelt cutter for my M3LR 2022 as there isnt any way of opening the backdoors in case of emergency where power goes out. Has someone ever tried these on Tesla windows? Do they work? I saw in another subredit (electric vehicles maybe) a post from someone who apparently had someone attempt to smash their kias windows with something similar, but the result was just small holes.
