Nice  but just don't work.
These are very nice holdfasts. No burrs or blemishes anywhere. The problem is that they will not work in a 3/4" benchdog hole. As the picture shows, the toe of the holdfast (red) is biting into the wood while the heel (green) is not in contact with the wood. There is not enough spring in the steel to allow the face of the holdfast to lay flat on the work. Less of a hook (angle of bend) would probably solve the problem but unless you have a torch, you're not going to cold bend this thing. It might work in a 1" benchdog hole but .....  I wanted to give this a higher star rating but if it doesn't work, what can you do?
Rating: 1 stars
