CRKT is an awesome brand. I have 2 of the crkt m16s, walmart style, they are nto what you should judge crkt on, they were specifically made cheap, with aus 4 blade steel. I bought one, got one free with another knife from a site.
But.... my crkt m21, 3" blade, aluminum handle, never leaves my pocket, it's my secondary edc. has a better grind for light work. mainly used on food and light tasks, but if you leave the normal grind on it, this is a great everything knife. The aluminum handles make the flipper work like a dream, if you have some torx bits you can easily remove the lawks system, it's separate from the rest of the mechanism. I recomend an m21 highly. M16, maybe an aluminum handle one, but I like a knife that fits my hand. The small m16 doesn't.
Other crkts I own. K.I.S.S. Least scary knife you can own, money clip, with a blade. Rollock weirdest lock, fun to play with. Ringed Razel, the perfect pocket fixed blade. Ultima 5", it was cheap, and I love the handle.
If I edc 2 crkts, I think they are a good enough brand to earn my trust, just steer clear of the zytel m-series knives.
