Hi all This object was in the garage of the house when I bought it 10 years ago. I've kept it around even though I really don't know what it is. Was doing a cleanup of the shop when I came across it again, and thought that the good people of RCM might be able t The half with the slots rotates relative to the have with the circular cutter, and is indexed so the center of the slot remains in the centerline of the cutter. I have no idea of it's age, but it's certainly at least 10 to 15 years old. Any ideas? ------------------------------------------------------------- I am not sure if anyone has named that skate sharpener in the whatsit files but a am sure that when we were kids 40 years ago we used this tool to keep an edge on our hockey skates. thanks for your time Glen Wallace
