Thread: Advice/Suggestions Needed--Losing Bevel After Initial Setting

Interesting. I'll have to try this. What's the explanation though, for example, if I can strop and shave off of the 1K but then can't shave off of the 5K level? How do I know if I don't have a good bevel set at the 1K level vs. doing something wrong at the 5K level (such as too much flexing as BobH mentioned)?

An added layer or two of tape can be helpful if the edge is not holding. Changing the angle just a tiny bit can sometimes give it enough strength to hold. But I'm not sure that is your problem. Slurry at 5k can back the edge off. Slurry can be useful. But the effects it has can be confusing. If you are evaluating the edge before you finish on the 5k clean (no slurry) you might be getting a false reading. Slurry backs the edge off. If you use it, you have to finish that stone on clean water before you see the full effect that the stone has to offer. You may already know that. I don't know. If you're truly losing the edge, a second layer of tape or even a third may help. But it won't change the need to use less pressure. Pressure is pressure.

I totally agree with above, if using synth slurry with each stone then finishing with clear water is a must if you want to truly see that stones potential. Otherwise the feel and performance of the edge with synth slurry will drop back a bit even though it is technically more refined at that stage.

I would re fresh the tape after bevel set. Just to rule out the potential of the problems that come with the wear from bevel setting.

Try just laying the razor flat on the stone with no additional pressure other than the pressure it takes to keep the spine and edge on the stone and do a few more than normal X strokes and see what that does.

Trial and error really helped me more forward even though sometimes I felt like I was going backwards.

If you are able to get a decent shave off the 1K (there are threads) but you are not able to shave off of the 5K the the most likely problem is too much pressure. At which point you would have to ink before the 5, as suggested, and chase a solution there. Personally I check after the 1K for my bevel set indicators and do not try sharp tests at each progression, but rely solely on the loupe as to when to progress. The ultimate judge is the shave test and I can get a comfortable shave from 1K up, and the 8K is very good. After the 8K it is more about the feel of the edge than a significant change in performance.
