9 inch tanto (tanto blade specifically won't break on bone contact) U pull down 200 on close grip pulldown let's say u can stab with an arm speed of 10mph that's 2000 lbs on the tip of blade that force will puncture anything on any human ever made even the densest bones will melt Now I advise and promote a pacifistic existence but I thought a good deal about this because sometimes I have to pull a bunch of heavy ass bookshelves and tables in front of my door cuz I'm paranoid someone will come in etc I get bad anxiety about it someone is after me I have to sleep with knives and hammers near me I would like a gun but I dont think I can get one
