I watched your video and I am aware of how to find the direction of the blade but I every now and then, after I determine it, I still get it inserted upside down. I have been told the same thing about making a finer tip on my blade but never seen it demonstated so now I know exactly how it is done, I will do that next time. As far as sanding off the oil residue on the blade to give it a better grip, I don't bother with it, but I used to when I had a blade that would slip out of my clamp and it was helpful. However, since I have changes the inserts on my clamps, (like I sent to you) I have found I do not need to reap on the clamp or even worry about the coating on the blade, as the blades do not slip out, even on the smallest of blades, any longer and only with a snug tightening. I never have to use any extra tension to secure the blade. I saw a video by Steve Good where he said one should change the inserts out at least twice a year and doing so, you do not need to exert an extra pressure to hold the blade from slipping and because of that, the clamp does not get bent out of shape, which is the reason the thumb screw and clamp wear out. It made my saw like new, when I replaced the clamp and the inserts. I do not think I will ever have to replace the clamp again as long as I change out the insert twice a year.
Thank you again for making the video for me. It is helpful and again, you are the man
