Somehow I’ve ended up with a cutting edge on my plane iron that isn’t square with the vertical edge of the iron.
Does anyone know if this is really a problem? Do I need to fix it or can I just adjust the angle of the blade with the angle lever doodad?
29 August 2017 at 7:13 pm #314742The #4 I use every day is like that, with the angle adjustment lever way over to the RHS. I keep meaning to sort it out.

Try to take note where you’re putting pressure on your iron and where you tend to spend the most time on the stone. In my case if I put 3 or 4 fingers evenly behind the cutting edge I notice I tend to wear the metal more on the trailing corner (if you hold the iron the way Paul does where the cutting edge is on a diagonal). If I adjust my finger placement more to the opposite corner, then that evens out just in a few sharpening sessions.
So it may be down to observing how you tend to hold the iron in relation to the stone, and seeing where you wear the metal. The make adjustments.

Since there’s so little steel right at the edge, it should only take one or two light passes. Test it with your Square and go until the edge is square to the sides. You should now have a bright reflective flat on the edge. Grind a new bevel until you see the bright flat disappear, then re-hone the edge and you’re good to go. Hope this is helpful.

Just a put a little extra pressure on the bad side of the iron when you sharpen up, it will come back to square over time. Or, put in some elbow grease and re-square it on some 80 grit wet-dry paper, working up the grits to hone it out once it is square again. If you have a grinder you can regrind it, too.
