Knex (very Sturdy) Combat Knife

this is my variant off of (credits to) "moxx's combat knife" notice the body is much the same but that the tip is nothing alike. also the inside mechanics to this knife keep it very sturdy. and it might be a new idea on the sight for knives? no clue, but i like it, althought the handle could be made better if anyone is up to the challenge.
