The Patch Knife
I repurposed a battered Old Hickory paring knife into a patch knife for black powder shooting. The lead ball is wrapped in a piece of fabric (the patch) which serves as a gasket. The fabric is cut to size using the patch knife.
Here's the original knife.
Why salvage it? Because Old Hickory knives have very good steel in them. They're worth saving.
The handle was splintery and helpfully said, "Vegetable" on the side. I removed it. Then I scribed onto the blade a 'roach belly' profile and took the blade to the grinder. Here are before and after pics. The deep blue layout dye allows me to see the scribed line.
I made a new handle out of some cherry I found in the shop. The handle is held to the blade by two brass rivets. I made the rivet burrs out of some brass strip stock and the rivets themselves from 1/8" brass round. I cut the diamond-shaped inlays into the handle using an X-Acto knife and a 1/8" chisel I made out of some bar stock.
Finally, I peened the rivets down, filed them smooth, and sanded one last time. The cherry was finished with oil and wax. Here's the result.
This is my first knife. I'm proud of it. Hopefully it will provide decades of service.
