Really? I see a lot of clipped folders around here in SoCal, along with SAKs on keys and a fair number of folding utility blade knives like the Milwaukee fastback. Traditionals aren’t super common in the wild, and belt carry seems almost reserved to bikers toting fixed blades of various sizes and construction workers with leatherman tools. The cowboy style pancake sheath carry mentioned above is basically non existent here or I’ve never seen it.
It's a big country.
The Milwaukee Fastback is super popular. It's cheap and the bit driver version is probably one of their best sellers, if not their #1. I remember when it first came out you couldn't find it in stock anywhere.
