Only have a large 21, and I carry and use it regularly. Often along side a sak, JK Knives pocket fixed blade or sodbuster.
My CRK is my "go to" knife, so much so that I put a small chip in the blade the other day and I just shrugged it off. It is a knife I bought to use, I wouldn't cry when I dinged the face of a new hammer. While most people consider CRKs to be on the pricey side, they are Fantastic pieces and the majority of users will come to see that, especially if they give One knife a fair shake over a lifespan measured in years.
