Thread: Black Hard Arkansas Stone?

I recently bought a Black Hard Arkansas stone and was curious what is the grit size. How do you figure this out? Experience? Comparing to known grit stones? It seems to put a polished edge on my razor but I'm not sure if I need something higher in grit to finish the razor. Under 60X microscope it looks better than my HSB & Co.'s OVB dry barber hone.

On a side note, does barber stones need to be flattened ... if so, what is the best way of doing that? Also, since I have not flattened the hone, would that be why the Arkansas stone makes the razor look better?

You should be able to finish a razor with the black Arkansas stone just remember they are very slow. You can lap a barbers hone with a DMT diamond plate. I dont assign grit ratings on naturals, the best test is the shave.

So ... 100 laps wouldn't be outta the question? Assuming that the bevel has been set correctly.

Would a 2500 grit wet/dry sandpaper work?

You cant go from bevel setting to the black Arkansas, you need a couple different grit stone in between. Sandpaper will work but i would start at a lower grit paper and go up!

Of course ... I didn't mean I would go from 1K to Arkansas. I was only curious if it could be used as a finishing stone.

What would be the transition of sandpaper? would 2500 be a finishing grit or a starting grit. I would think either a finishing grit or close to it. However, I couldn't see going down to a 400 to start.

Perhaps lower like a 225 wet/dry sandpaper and go up!

Get a cup of coffee when you start to lap the black Arkansas. You'll see why "hard" is a part of the description!!

I don't usually lap barber hones unless they are really dished. IME, years ago, barbers didn't lap them. I think washing them with a nylon bristle brush and trying them is your best bet. I lay a straight edge on them to check them first. If I do lap them I used to use a 325 diamond plate but went to 120 (DMT D8XX) to save a lot of time. If I was going to lap a barber hone with sandpaper I would start that low and work up to get it smooth as possible. 1k sandpaper would be as high as I would go. YMMV.

The hard black ark has been good for me with an already shave ready razor. Improving the edge I mean.
