One thing that I notice on my WE, and I assume all do, that can cause the blade to cant left is the clamping action itself. As the bottom screw is tightened it creates incredible bending (and clamping) force, moving the uppermost part of the clamp jaws to the left. That movement is amplified if the top screw is not sufficiently tightened. Clamp and watch the blade closely as the bottom screw is tightened and you will see the blade rotate to the left as the clamp jaws flex to the left. I don’t see this as a problem. Rather, the point is that the lower screw exerts incredible bending and clamping force and as it does it also torques the clamp jaws to the left. This makes sense – as the bottom of the right jaw moves to the right, the top must move to the left. To limit that rotation, the top screw must be tightened completely, and securely.
I think. Or am I missing something?
Incredible information! And thanks so much everyone for taking the time to respond. I agree that as the bottom screw is tightened it moves the blade even farther. I did some checking with the angle cube attached as I tightened the bottom screw and it definitely moves the blade as it is tightened. I am not worried about the fact that it moves, only how to adjust the stones. Now that I understand that a little better life is moving along nicely π
08/17/2014 at 7:23 pm #19988Thank you Sir. Your post on the knife sharpening class you took inspired me to find a class at the Phoenix Knife Shop, which I am going to take next month. I have never been able to get anything resembling a sharp edge by hand, but the knowledge I am gaining here is starting to make me think I might be able to get closer with some instruction. I also appreciate you saying you fumble with the math. Perhaps you might clear something up for me. In the picture above it shows a cant to the left of 3.2 degree. If I am figuring it right, and that is a big if, it seems to me that in order to address a 20 degree edge correctly I should have the left stone at 16.8 and the right at 23.2. Is that correct or am I off my rocker?

08/16/2014 at 6:21 am #19949I have that same blade mounted in the clamp currently and the angle cube is showing 1.45 degrees of cant? I am clueless….. And no, the stone is not resting on the angle cube π
07/31/2014 at 10:31 pm #19667Thanks everyone. I may have misled you. The fact that I got great results by knife number 5 is more about me not being very good at sharpening than it is about what great edges I have been getting. π A couple of experiences yesterday humbled me somewhat and let me know that I have so much more left to learn. That is OK with me. More questions will be forthcoming.
07/30/2014 at 5:41 am #19627I may do that once I retire π I am a firefighter and carry that Blur on shift. I pry doors open with that thing all the time. The rounded tip is perfect for those cheap Kwikset locks on garage and interior doors. It is much better than torching my point constantly on lock bolts π Very well done Sir.
