Thread: Question about damaged blade.

I was wondering if it's possible to tell if the blade has been damaged by heat just by looking at it. Any help is most appreciated.

If there is a darkened blue color in sort of a rainbow gradient effect, that is the usual sign.

There doesn't seem to be. If it is heat damaged though, would that cause it to feel sharp but then when I try to shave it won't do anything, just feel duller than a butter knife?

Have you been doing any grinding/sanding/buffing on this razor?

Whats the story here......?

When you say "cause it to FEEL sharp", what do you mean? What are you doing to determine pre-shave sharpness?

Also, are there any pics?

Sounds like it could be. The heat damaged razors I've dealt with will take and edge up to about 1000 grit. The edge just breaks down after that on finer stones.

Even the edge from the 1000 grit or less is really brittle. If you have a loupe you can run your thumb against it and see it "get toothy" I guess you could say. You should be able to see differences between it and a undamaged razor with a loupe even without doing that. If I'm remembering right, you will always be able to see the front of the edge in the loupe, for instance. The edge never gets fine enough that it doesn't reflect light.

It shouldnt have passed any HHT/shaving tests either, except maybe shaving arm/leg hair-but I don't think they'll usually even do that.

personally..send it out to a reputable honemeister to tell you exactly whats what
