mlapaglia Report post Posted September 9, 2011 (edited) I have the Tandy Diamond Awl that goes into the handle with the metal chuck. I need to sharpen it and want to know if I should just sharpen the first 1/4", like it currently is or sharpen both sides all the way down. Any help or information is appreciated.

JohnD Report post Posted September 10, 2011 I would usually only sharpen tip and polish the whole blade. I tried a search but couldn't find it, but somewhere on here is a lengthy thread(one of many, I'm sure), with a ton of info on awl blades and hand sewing. I forget who wrote it and I apologize for not being able to credit the author, but it was said that an effective awl shape would be a sharpened diamond shaped tip with an oval or oblong shaft. Both the tip and the shaft should be highly polished. Only the tip needs to cut the leather. Although I should add: I bought an awl blade from Bob Douglass a few years back and have only had to polish it every once in a while. Worth every penny.

TwinOaks Report post Posted September 10, 2011 Don't over sharpen the sides of the awl. The shape pushes the leather out of the way when you make the hole, and then the leather closes up around the thread. If you cut the leather (sharpened sides) the hole won't close up as much.

bruce johnson Report post Posted September 10, 2011 Several years ago I had the good fortune to have an older Irish harnessmaker spent the afternoon with me. The first thing he did was to take a shoeing rasp to my stitching horse to properly shape the ends for closer sewing. Then he took my awls and sorted through them. He picked about 5 out that were OK to his purposes, and went to sharpening. Muscle memory and all that, but about one minute each on the stones going through the grits. He raised a bur edge on the actute angles of the diamonds almost to where the taper leveled out. Stropped the bur off and then used that edge to cut leather as a test. Used them like a knife on a the edge of a piece of skirting. They sliced like a good knife. I just thought I knew how sharp they were supposed to be before that. THAT was a lesson learned. One bad awl he worked into a round point to use for oversewing with less chance of cutting the existing threads. The rest went to sharp points for a game of "awl darts". .

Hope this helps, Once I can afford it I need to get one from Bob Douglass. Thanks. Don't over sharpen the sides of the awl. The shape pushes the leather out of the way when you make the hole, and then the leather closes up around the thread. If you cut the leather (sharpened sides) the hole won't close up as much. That was the thought that made me question sharpening the edges. Thanks for the info. Several years ago I had the good fortune to have an older Irish harnessmaker spent the afternoon with me.

Id love to be able to "Sit at the feet" of someone who has done this for years. You were really lucky to have that chance. Quote Share this post Link to post Share on other sites
TwinOaks Report post Posted September 10, 2011 As I've said several times on here, your awl point should be sharp enough to get at least halfway through your finger before you feel it. Quote Share this post Link to post Share on other sites
