I bought this razor off ebay, a Simmons hdwe Keen Kutter. It's a nice razor but it came really dull. While trying to hone it up I noticed that the edge was chipping away near the tip of the blade. Does anyone know the cause of this and what I can do to correct it??
What hone are you using to hone it up? Are you trying to set a new bevel?
I'm using a Norton 4000/8000, and yeah, right now I'm trying to set the bevel.
Does the blade have pitting or tiny little holes you can see in the blades surface?
It's a common problem on carbon steel blades that have rusted badly, but not a usual problem on stainless blades.
It's all according to how deep the chips are. It will take a very long time with the Norton 4K. A 1K would be a much better choice for repair like that. This one might be a candidate for the bread knife treatment to get rid of the chips.Quote:

A small radius or chamfer on the edges can help eliminate problems as the blade passes over the edge when you are making your stroke. Theoretically, if the stone is flat and the blade is straight (and held perfectly flat on the hone) it shouldn't make any difference, but I like to have a small radius on my hones.
Go with a coarser stone and less pressure to grind past chips. I had an old W&B once that wouldn't stop chipping now matter how delicately I worked on it.

Thanks for the tips guys!
I assume that you looked at it under magnification when you got it ? If it didn't have chips at that time and the chips came from honing perhaps it is a pressure issue ? Were you bearing down on it ? If it had chips to start with you can hone them out flat with patience and persistence. I have breadknifed a few but it can take as much honing to get the bevel back as it would have to just flat hone it to start with . Sometimes more sometimes less.
Like XMan said, I've encountered a razor where it just kept microchipping. I couldn't figure out why it it wouldn't take a sharpening until I bought one of those radio shack magnified loupes. I'd see the microchipping, hone it, get more chips. I tried to do feather light strokes on a higher stone to no effect.
I kept wondering if it got de-tempered (if that's a word), or if something happened to the steel to crystallize it or something. Maybe it was just age and deteriation. It was an ebay cheapie (not a Pakistan razor), so I just tossed it into the mug with the other troubled citizens of my collection in the hopes of someday solving the puzzle.

Just a thought, celebrated razor maker Joe Chandler gave a review of his then newly acquired Shapton GlassStones awhile ago. He was very impressed with the Shaptons. In reference to the microchipping this is what he said at the end of the review ;Quote:

Wackers, for instance, because they're so hard and "chippy" seem to love the TOS's. It cuts and hones without microchipping, which I had a lot of problems with on other, more aggressive hones".
If you have a natural as described above get that chippy razor out and maybe that will solve the problem. :hmmm:
Looking forward to your entry here!Quote:

I had a razor like that and the thing was driving me crazy, had to swallow my pride and PM Glen/GSSixgun and heres what he explained to me(not verbatim) under the surface corrosion, the more you hone the more its exposed, you just gotta keep going until you or it are gone. The razor would look like a primitive saw under the glass, you would get it ooooh so close to perfection and then the edge would just crumble, and you would have to start over, its a ****er.
Well I actually dulled the edge down on my Norton. Then I went to the hardware store and got some sheets of 1500grit wet and dry. The 1500grit I taped to a my countertop and set the bevel with that. I think it was surface corrosion since there was some staining around the edge. I had to dull it and then re-hone it several times, soon it began to hone without chipping. Last night after spending all afternoon working on it I got it up to snuff. After my shower I shaved with it and it was extremely smooth :) Might even shave better then my Friodur. So it took a ton of work, but I finally got it to be a usefull tool.
