I'm a carrier also, have been since high school in the sixties. Carry a 2 1/2 in. Old Timer. Have several smaller ones but this one has the heft that feels right! As a retired wood shop teacher I'd never be without one. My last year teaching I pulled it out of my pocket to trim a broken fingernail, while doing lunch duty. My (younger) principal noticed it and was beside himself that I had a knife in school. What's this world coming to? Ron
