Answer to John's inquiry about stabbing tool:
This a before and after shot. I heated the tip red, straightened it, and made a punch out of it. Yesterday, I ground it into a stabbing-in tool.
This is the tool at work. It is not a flat chisel, but has a lens (convex) shape. The tip too is rounded and polished. It is very sharp.
The tool on edge. It is about 5/64" wide. In use, I pressed it into the wood, rocking it along it's length a little. then I withdrew it, and placed half of the edge back into the cut previously made, and pressed down again. Repeat this, following the curved line.
I have some dental scalers with chubbier handles, and intend to make a few more of these. the tool I pictured is only about 1/4" in diameter in the handle part, and not easy to use. Also, I'll cut the new projects in half so get two from a scaler. I can also then add a button on the end of the handle to better aid in the stabbing process.
