About 3 inches and 3 onces is reaching my limit in front pocket carry. I always carry right front pocket, and could never got used to a back pocket carry. I don't like either weight or bulk in a pocket knife, I carry so much other stuff that a small knife is nice. There's a Bison aluminum capsule with some arthritis meds, Fenix EO1 flashlight, Bic lighter, tobacco pouch, pipe tamper/tool, mini bottle of hand sanitizer, golf pencil with rubber band on it, 2 bandana's, wallet, plastic doggie bags, keyring, so my pockets are close to capacity most of the time. I like stuff as compact as I can get it and still function at designed task. Small knives are in the category. I guess that's why I like peanut size knives.
Peanuts, pocket hunters, mini trappers, Eisenhower's, 58mm sak's, all good. Much bigger and I have to start thinking hard if I really need it. I live in jeans except for dress up occasions like weddings and funerals once or twice a year, so this stuff carries well. Dress pants I have to streamline and go light. Although I've been getting more into mil spec cargo pants this past two years, and I fond the an object can be bulky but light and still carry well. Like a number 8 Opinel can drop into the leg pocket of fatigue pants and go un noticed because of the light weight. And the button closed pockets don't dump stuff while sitting.
