my first buck, it was either a small stockman or 503 not sure which was first. My newest, well I'm not sure it qualifies as used, I picked up this user off the exchange. I'm not sure why I've never had a 301, always thought it was to big, but a few weeks ago I was carry another traditional large jack measuring a hair over 4 inches coming in at over 4 ounces. And realized that the 301 was actually smaller. So here we are.
