I bought several of these a couple years ago so I've had plenty of time to observe their wear. For the price I paid for them I think they are perfect. I would however like to advise other instructors to not intentionally hit anybody with the knives as they will become feeble after rough usage. And also the outer layer of paint will easily rub off so for the buyers sake, buff the knife gently with a rag before putting them up for sale/practice.
