How fortuitous that this post came up as I was thinks my of making a similar post...
I have the Tandy awl, the lower end one. It isn't very good. I managed to sharpen and polish it enough for it to be serviceable... But my major complaint is that it's just too big for most of my work. It truly seems to be intended for heavy stitching on heavy goods.
I suppose I could grind, sharpen, and polish it down to a more usable size but I would rather spend a little money and have something that I don't have to build from scratch.
My other option is to make my own... I have a handful of German made blades from an old industrial Wagner metal cutting circular saw. I have played around with cutting out pieces and working them down to make my own awl. They're HSS though, so I'm not sure how good my end product would be.
I will check out the products James Rogers noted... However, it seems the Douglas awls are all as big or bigger than the one I am currently using.
