Watched a talk about shop safety for some of the beginners in a woodworking group. The same speaker then talked about some shop made tools and showed some. His scratch awl was very sharp and had the usual palm handle, with not flat spot on the round handle to prevent it from rolling off the bench. In summer I usually wear flipflops in the shop. The one thing I learned the hardway many years ago is make sure the sharps can't fall off the bench. I don't believe I even have a round handled screw driver that rolls. My lathe tools are kept on a music stand sort of thing with strong magnetic strips that hold them in place. I have that to my left next to the lathe head stock for easy reach.
