I have just purchase a set of Kelton Hollowing tools,with three tools,
curve, straight and slightly curved. They fit into a large metal handle and
held in place with set screws. I was wondering how do I sharpen these tools.
The end are made of heavy steel with an end shape like a scrapper. I have
two or three diamond pads but I am not sure how to sharpen. Any suggestions
