Hello,
I've looked at older samples of the Marples blue chip chisels, and the side bevels are ground almost to the face, the side face even along the entire length.
A recent sample of chisels I've seen have the bevel very high up and somewhat angled, ground to maybe 2mm of the face at the tip, less than half the thickness at the middle, and are effectively useless for doing tight-quarters maneuvers such as cleaning up dovetails.
Has anybody else noticed this? Is this the new style of grinding that Irwin tools is doing for these chisels?
Thanks!
