I recently bought a set of the new perfect-pattern chisels from LV, because they looked really interesting. In fact they are nice to see up close and feel nice in my hand. They seem to have been ground at 25 degrees.
The first chisel out of the box though had a damaged corner, as though it had hit the milling machine wrong. I normally sharpen now freehand, but since the edge was going to need so much work, I pulled out my MKII and used that.
After a lot of work, I had a proper edge. Took the chisel to some end grain pine, and it pared nicely. Then chopped a shallow mortise in pine, about a minute’s worth, and looked at the edge. It was very damaged, looked like the edge of a serrated knife.
I had not put a micro/secondary bevel on it with the MKII, I just didn’t think to.
I resharpened the edge using my normal freehand way, which normally makes a very slight convexity. Sharpening the damaged chisel this way, the edge holds up to chopping just fine.
I tried a second chisel from the box, and with no secondary bevel, it became damaged just the same.
So are these chisels poorly made? If a chisel edge is easily damaged at 25 degrees, just because it has only a primary bevel, is that a defect?
They are not described as paring chisels.
