4 Replacement Blades for the Hock Scratch Stock Tool. In the old days, decorative beads could be applied to the front of a drawer, cabinet or door with a tool called a Scratch Stock. In simple terms, this involved a piece of wood (handle and fence) with the means to hold a steel blade with a profile cut into it which, when drawn across another piece of wood (like a drawer front), would create the inverse profile on the wood. We spoke to noted blade maker Ron Hock about it, and he came up with the tool and spring steel blades to be used as replacements or to make a complete tool.
