So I have a Work Sharp 3000, and I’ve been using it to sharpen my chisels. Keep in mind that I have very limited experience with sharpening in general. I’ve always flattened the back with some sandpaper and MDF, and honed the bevel with one of those $15 honing jigs. It worked reasonably well, but I’ve only ever used cheap chisels from Harbor Freight.
Well I wanted to step it up a bit, so I bought the Stanley Sweetheart set of 4. They seemed reasonably sharp out of the box, but not quite as sharp as freshly honed Harbor Freight chisels. I decided to sharpen them with the Work Sharp.
It has been my experience that the WS3K removes a ton of metal in a short amount of time. When I try to flatten the back, it leaves a very defined swirl on the back of the chisel. If you run your hand over it, you can feel the bump.
I know a lot of people say that you only need to flatten a n inch or so on the back, but doesn’t that groove bother you? It seems like you would never be able to get a flat reference for paring or fine chisel work. Is this just the way it is? I only did a tiny bit on my 1” Sweetheart, and decided to hold off. I really don’t want to ruin a $100 set of chisels.
The other thing is, how can you tell when it’s really sharp? I’ve never actually felt a scary sharp chisel (16000 grit or so), so I really have nothing to compare it to when I sharpen mine. If I try to shave my arm hairs, it pulls a little before removing them. I certainly would prefer a razor if I had to shave, so my instinct tells me that it isn’t that sharp.
The worksharp seems to get overwhelmingly positive reviews, so I must be doing something wrong.
