I get this is a budget knife but dang the action on this is nothing like I ever knew possible..... and shave sharp right outta the box. It's not a tri-ad lock just a simple leaf spring with a secondary manual safety lock. Plastic / polymer scales. The blade shape, the action, the lock up, the grind, the ergo.....main i am hella happy. If I am this happy with a budget knife how much better are these mega-$$$ knives. On the one hand I don't want to buy one and risk disappointment OTOH I want to buy one to see the difference. I spend every other second flipping it open. I got a huge callous on my thumb from unlocking it and closing it one handed but that action has gotten easier or i have gotten better. I got the short blade, paid way above what I could have online. Does anyone know what the liner and leaf spring are made out of, it looks like grey plastic. I really can't tell if it's metal or not. Finally what's a good online knife shop that ships internationally.
