Any of the Emerson Snubby models. Especially the waved variety. Full size handles, titanium liner lock, G-10 scales, and the fastest opening of any folder. Also US made. Prices are on the steep side, but if you shop around deals can be had. My buddy picked up a mini CQC-7 new for 100$. I like their larger knives, I have a Commander, CQC-7, Combat Karambit and they are all tank tough.( I am hard on my knives)
I have Benchmades, Spyderco, Zero tolerance, Microtech. I EDC a Emerson more often than not. Good luck finding something that fits your needs!
