Thanked: 4822Looks good. I’m surprised you are making a mono steel razor. I love your grinding.

It certainly looks likely!
What are your impressions?

Thanked: 4200+1 Shaun,, I always enjoy looking at the profile of Victors blades.

Is that a 7/8 blade?
What wheels are you using for the grind?

I am amazed at your full hollows. Cannot find people near me with razor experience. Do you use the 4” and create a holow grind then use the smaller wheel to take it down near the spine? I would love to watch you grind one. My first ones were heavy at the edge, I am improving but still get nervous.
do you grind edge up or edge down?

Thanked: 44Well if you're ever in MT send a PM and spend a day in my shop.
Not sure how Blueman does it but I start with a large wheel that grinds from the edge up toward the spine but not all the way, then you go into the spine area with a smaller wheel. Once done you're left with two crisp grinds and the belly which you can then grind away some with a third operation before blending. I watched a bunch of razor grinding videos to figure it all out as well as an old Soviet razor grinding manual and it seems that's how it's done in the factories. There's a good 3 part series of videos filmed at Wacker Solingen where they show grinding the belly and then blending over with a wheel made from walrus leather using a slurry of oil and emery powder.
The hardest thing is getting a nice uniform line when grinding the two hollows, easier to do with a double wheel grinder but not so easy on a regular 2x72 just using your hands. If the line isn't straight, even when you blend the belly, when you move the blade in the light you get a wavy, undulating reflection which looks kind of ugly.
You really need to grind as close to an apex as possible to get the thinness at the edge. On some razors as I'm going into the finer grits I might even get a very slight burr on the edge. Even on wedge blades I grind thin enough to flex the edge over the thumb. If you leave them too thick when you go to set a bevel it ends up too wide then you have to go back and grind more. I only like to set the bevel at the end of all the grinding operations so I get everything as thin as possible but some people like to do some of the grinding, set the bevel, then go back to make the bevel thin and even. I don't like grinding a razor/knife that has an edge on though for safety reasons.

Yes the 4.5" wheel creates a half hollow on a 7/8 blank and the smaller wheel removes material near the spine and creates the belly. I used to blend those two radii to get rid of the grind line near the edge, but then I decided that I should emphasize it.
I grind edge up.
