actually, kosher has a LOT of ... for lack of better terms... weird rules. such as the food (dunno if it applies to weed... can weed even be kosher?) can not be torn. So if the knife used to cut meat has a nick in it, and tears the meat instead of slicing it... game over, not kosher. of course.. thats down to the nitty gritty bullshit rules that 1 or 2 peoplei n the world follow lol.
