My medium-large folders, when I'm in the mood, are the (a) Kershaw "Spec Bump" S30V, (b) the CRKT "Desert Cruiser", (c) Gerber "Gator 2" (hunting only), and (d) the Gerber "Applegate-Fairbairn Combat" folder.
My medium folders are (a) the Kershaw "Avalanche" S30V, (b) Imperial/Schrade "Oldtimer 70T Cavebear", and (c) Kershaw "Needs Work" Sandvik 13C26.
My small folders are (a) Kershaw "Leek" S30V, (b) Outdoor Edge / Seki "Pocket Lite", (c) Gerber "Applegate-Fairbairn Mini Covert", and (d) another Kershaw "Leek" with 440A.
The most common carry are all Kershaws: Spec Bump, Leek, and Avalanche.
Spyderco should sue Benchmade for that one version of the mini-Griptilian where they are clearly leeching off of Spyderco's distinctive blade geometry with the big hole.
