Thread: Improper bevel development

Thanks for your help again.

All during the honing I was testing the edge with the HHT, arm hair, thumbnail test, thumb pad test.

At no point did it "feel" sharp. It has never passed the HHT and only cuts a few of my arm hairs, unlike my properly honed razors.

Also, it does not seem to exhibit any of the overhoning characteristics such as a roughness on the back of the thumbnail or thumbpad test. And no square chips in the blade edge.

It never occured to me that this would be over honed, but maybe you are right? Is there any definitive test for that?

Thanks,
Chad

Do NOT do the thumbnail test anymore as it will dull the edge that you are trying so hard to polish. The thumbnail test should only done in the early stages of honing a razor to test to see whether a good initial bevel has been established. You can use the thumbpad test or the hanging hair test to compare your edge to your professionally honed razors at this stage because they will not damage the edge; however, they are just tests. Different razors with different grinds and steels will react differently to these tests so the real test should be the shave test. If you have been doing the thumbnail test up till this point I might suggest doing a 5-5, 3-3, 1-3, 1-5 pyramid instead of the 3-3 (the 3-3 might be enough though). then do 10-20 passes on the coticule followed by 10-20 passes on the chromium oxide. Strop the razor and test shave. If you are close but not there then do another 10 passes on the .5 paste. If that does not get you there then do another 1-3, 1-5 on the Norton followed by the coticule then the paste again. It sounds like you are getting very close so you don't want to do too many passes. Like I said earlier if you need any more help feel free to give me a call.

I'm going to jump in here and suggest something unorthadox. Since you have a coticule, you could just stick with that instead of going to the Norton. The coticule is a slow hone, and it's difficult to overhone with it. When I'm having trouble with a wire edge, I grab the coticule and use my rubbing stone to build up a nice slurry. The coticule seems to just clean off the wire slowly and bring up a beautiful edge. (Some members use a coticule exclusively to hone their razors.)

If it's pretty close to shave-ready, build a slurry and do 30 strokes. Test on your arm hair. If you're near shave-ready, it should slice arm hair effortlessly. Keep doing this until you're able to easily shave arm hair. Then clean off the slurry and do 10 to 20 strokes on the clean, wet stone. That puts a final polish on the edge.

The Norton is a great stone, but sometimes I wonder if a coticule wouldn't be a better choice for someone just starting out with honing...

Just a thought,

Ok I think my technique is just terrible or something. I did the 5-5 pyramid then spent some time on the coticule. The bevel looks great under the microscope but it is dull as heck. I put the thumbpad test and it doesn't even cut in. I can put a pound or two of pressure and it won't even cut into my thumbpad.

I don't think I am rolling the edge into the hone at the end of the stroke, but I am going to start lifting the edge at the end of my stroke just to see if that fixes it.

You guys are killing me!
