Looking for a low profile back up speed assist knife. How good and strong are these zero tolerance knives?

Currently carry kershaw speed safe in rear pocket but want a more combat style knive.

Also like this spyder co titanium but not sure how strong it is. Want something stronger than my CRKT M16-14SFG.

they are pretty good for the money. However, it's a big knife. I dont know about carry that everyday on my back pocket.

Yeah,that ZT looks to be very similar in size to my 0200.The blade is a little shorter but the closed length is the same and it weighs more.

They're far from what I would call "low profile".It's the biggest folder I own...Makes my Rift(my 2nd largest folder) look tiny.

Nice knives though.
