Bama, I'm NOT saying that my way is the way, at all. This stabbing tool is inspired by the late Gary Brumfield's little stabbing tool. Your observation is correct in that I push the tool into the work, and rock it forward. This avoids the 'elbows' you speak of.
Jim Kibler posted a while back about the set of gouges for cutting the proper radii, and his is an argument based on a very long history and tradition that I have no argument with. Professional furniture carvers had all these tools at hand, and were proficient at carving. The right gouge saves time, therefore, you were better able to compete.
Jim Kibler sets the gouges in with a rocking motion, as I recall. His gouges are not the deep 'U', but partial curves. Most of my gouges are the deep U shape, so I can't make a partial curve with it. If I ground the legs of the U off, I could use them for stabbing in. But I'm not about to do that.
