Thread: Need help with a frown in a blade

Would the same technique be used to remove a corrosion patch on the edge?

That would be overkill, of course depending on the "patch" you do have to have clean steel in the end, but usually I have never needed more than 20 degrees and circles in the worst case razors..

I will post one into this thread. (Corrosion has eaten away a 12mm W x 0.5mm D patch on the edge leaving it sawtooth about 2/3 toward the heel.)

Removing the frown required removal of a lot of material to correct the situation. I do not think your situation is as drastic but will not know until you post a picture. But my guess would be +1 on what Glen said. Instead of a nearly 45 degree angle, you will probably need a much smaller angle. Point 5 mm is substantially less the the 2+ mm I needed to remove. I'll be interested in seeing your picture.

Yeah, the 45 draw thing is for removing alot of material. I mainly use a draw b/c I do it on a really coarse DMT and the edge will catch on the grit if the blade goes forward. Fast, though. It also seems to help keep the blade's shape well, but that could just be personal preference. Of course, you do need to clean the blade up on a progression if using something that coarse, and check with a loupe to make sure everything is kosher. Prolly not something you want to do for the first time on anything but a junk blade, its pretty aggressive.
