I've been looking for a new edc folder, mostly at benchmades and spydercos. A lot of them come with reversible clips, but some, (eg. the BM grip) don't. I've been edc-ing a kershaw scalllion (tip-down only, 3.5 in. handle, AO with flipper), and from my limited experience, it seems like tip-down might work better for larger knives and tip-up better for smaller knives. I've never owned a decent quality, manual thumb-stud knife, and I've never used anything with thumb holes. I was surprised I couldn't find any threads on these debates searching this forum. I'll probably test drive whatever knives in a store before I buy one, but I'm interested in hearing your opinions.
