Thread: Edge collapsing halfway through shave?

If there are better angles for pictures I will take them tonight after work and post them. I will try a few more passes on the 12k strop and try another shave in the morning.

Well, I think some of the posts may have saved me some trouble in the future if I get some higher grit stones.

He corrected himself in post #2, so there wasn't any need.

Some better photos of the edge would help, but your bevels do not look like 12k Super Stone bevels.

What are you stropping on, and did you lap your stones and bevel the edges?

I will get some better pictures of the edge. I lap my stones wit the course DMT diamond. I do chamfer the edges/corners as well. I strop with a SRD 3 inch but don't remember which type of leather it is though.

The first step is to determine whether or not the bevel is set. Since you've got a loupe, examine BOTH bevels and see if their scratch patterns extend ALL the way to the edge along the entire edge. If not, then the bevel is not set and you need to go back to the 1k. If the bevels DO appear to be set, then focus on the edge and examine that along the entire length. Let us know what you see.

I will go back and look. I am pretty sure the bevels meet when looking on both sides.

I too suspect that they will. I have a hard time imagining how an incomplete bevel set can lead to a "collapsing edge."

Looking at the sides will not tell you if the bevels are meeting, it will tell you if you are honing to the edge, but not meeting. But if you are not honing to the edge, the bevels will never meet.

Look straight down on the edge, to see if they are meeting. They must meet at 1k, then refine and not chip or collapsing on each stone. The goal is to make the edge straighter with each stone in the progression.

This thread shows what the edge should look like, post 41.

It looks like your razor has a slight frown. That may be the problem. The bevel on the narrowest part of the blade will most likely not be in touch with the hone.

I think I'm seeing that as well, what could be happening is the stropping is bringing that part of the blade back just enough to feel alright at the beginning of the shave and die quickly.

Hold the blade edge down on a lapped hone and hold it up to a light and see if you see any light coming through under the center of the blade and not the ends, rock the blade slightly if you have to.
