They are 20% thicker, which reduces blade chatter. Their high-carbon content and Rc62 hardness (standard blades are Rc58±) will provide a long-lasting, fine edge. These blades are also easier to hone than blades alloyed with tungsten or chromium.
The regular blades fit most production planes. The 4-1/4" long block plane blades have rear depth-adjustment grooves. Blades with the 7/16" slot fit both Record and older American-made Stanley block planes. Blades with the 5/8" slot fit current British-made Stanley block planes (the planes we carry). The spokeshave blades fit both Record and Stanley models.
These are excellent quality, performance enhancing blades. Final honing required.
The Hock replacement blades are not stocked at our retail stores, but can be ordered for pick-up.
