Hard Arkansas

Hello Gentlemen,

I recently bought a 12x3 Hard Ark from Dan's Wetstone too. It's a huge work surface and I can get a seriously keen edge off of it, passes the HHT3 straight off the stone, but it's not as comfortable/smooth as I like. I'm gong to keep working with it and try to find that happy medium between sharp and comfortable. I may have to use it as the 4 stone and just calm the edge a bit with a C12K or Koppa finsher. More to come.

Is it a hard ark or a black or translucent ark. If it's a hard then I treat them more like a pre finisher although I have known a few people who finish on the regular hard arks. Smoothness comes with the stone wearing down. And with a 12x3 that might take a while. I recently bought 2 large arks pictured earlier in the thread and they are taking forever to get them where I want

Wow!!! 36 Square Inches of Hard Novaculite, and that's just One Side of the stone.

I still think of an 8" x 2" as being a large stone.

12" x 3"?

Guys, It's not like that, I just wanted a big stone.

Have you done anything to the stone? Most folks like to dress them up on wet/dry sandpaper up to 2K or so then take a cleaver or chisel to them to shine them up a bit.

Very nice stone.

I've had this stone for about two weeks and I'm not familar with dressing them up? Can you provide me a little information on that process?

Big Greg

What I do is; start out with lower grit ( I use SiC powered) 220 then 400 then go to wet/dry sandpaper and work my way up to 2000 grit. After that I take a cleaver or wood chisel and work the stone till I see a nice glaze form.

That will slow down the stone but yet smooth out the finish.

I will try this process when I get back in country in few months, thanks.

It is basically the same lapping and burnishing process used on any hard stone or barber hone.

lap the stone flat with your preferred method, most use a dmt 325. Wet and dry paper on a counter or piece of glass will substitute.

Continue lapping up the grits as far as possible.

For final burnishing use another hard high grit stone or a large bit of tool steel. Tool steel is not hard enough to do this quickly so I suggest a 1x3 ark to burnish and later raise a imperceptible slurry. Don't expect good results using ark slurry with razors, but great results can be had with other less sensitive edges. I usually use about 200 passes to burnish and ~50 to raise an arkie slurry.
