Thread: F.A. Koch Help! heat damage?

I'm new to the art, and just picked up a F.A. Koch & Co Faultless 116 from an antique store. In the store it looked to be in great shape (though I will be the first to admit, I am no judge of steel at this point). However, when I got home and looked at it in different light, I noticed some discoloration on the blade (possibly from being heated?). I do know that this could be fatal to a blade, but I don't want to toss it just yet. Any second opinions?

The first two pictures are what the blade looked like under the light at the store (or at least what I saw). The next two show the discoloration. Am I just seeing things, or does it look like a problem?




Cheers
