Interesting read. Especially the comments. I was hesitant to give this any energy, but here goes. I have aways used my cabinet scraper with the positive hook facing the clamping bar. I have never heard anyone suggest otherwise until I read this article. (I thought bevel up/bevel down you never know.) So I tried it out, and the reverse method didn’t do anything. Then I loaded the blade in according to the manufacturer’s specifications and it worked for me.
