Thanked: 7It really wasn't as bad as I thought. Went through a couple sheets of Norton ProSand 60 and 100 grit. The sheets were destroyed afterwards but they were able to get a good bite and the stone is now flat on one side with beveled edges. At very steep angles there's already a reflective surface.
Next is to keep working through some higher grits to achieve a nice polish. Then start burnishing with an old gold dollar I have.
Already have a couple decent coticule. I like them a lot. This stone was inexpensive and is the same size as my DMT bbw and coticule. I think it will help me get to the next level after the coticule.

Thanked: 580You really need something a bit more solid like a carbon knife or cleaver that you can get some pressure on. I used a blade out of a plane.

Thanked: 3215It’s not so much the reflectivity of the stone, it is the smoothness.
When you burnish with a hard edge, like a large carbon, kitchen knife, cleaver or wide plane blade, you will feel any rough spots. You can also hear them.
Keep working those spots until the whole stone face is smooth. Then try a razor on the stone, you want honing performance, not necessarily the shiniest stone.

Thanked: 7Euclid I am thinking that as well. Lapped up to 800 grit and while reflective it is nowhere near mirror. It extremely smooth though. Took my favorite carbon Japanese knife and went to town with x and half strokes. 2 birds with one stone as it were. The stone is getting smoother and shinier and my knife was getting better by the second. Just finished slicing tomatoes for burgers and while not shaving sharp it is still wicked sharp with a highly polished bevel. Win win. I figure the stone is good to go for now and will improve with use. Have a drawer full of carbon and stainless knives I need to work through and the stone and knives will get just that much better.

Thanked: 246Burnishing the stone will make it more reflective. Basically burnishing dulls the abrasive particles, which makes them take a flatter or rounded edge, and that will cause them to reflect more light. All stones will pretty much reflect at a steep angle, this is just refraction. If you want to speed up the burnishing, use water when doing the burnishing.

Thanked: 7So I used a razor that was last used on my welsh slates a few months ago. The edge gas falling off for some time now and was due for a refresh. I ran it over the ark with x and half strokes for about 8-10 minutes this morning. No lap counting just go go go. Checked it under my 60x scope. There was obvious improvement to the edge. Toothiness was visibly reduced and the bevel was highly polished. Stropped on nylon and leather and checked on arm hair it was cutting effortlessly. 2 pass shave was smooth and clean. Minimal irritation.
Very impressed. I think this stone still has a little way to go and this razor is still due for a proper refresh but with just 10 minutes on the ark a notable difference was made. I see good things with this stone in my future.

A good hard Ark is an interesting hone.
With use an Ark will be smoother and smoother over time and move from
abrasive to more of a burnishing rock (plastic flow). If you saw, sand
or lap an Ark it will have texture the way a steel file has teeth and like
a file be abrasive. With use it will be less abrasive and more of a dull
burnishing tool. This is ideal for many razors....
The best surface conditioner is any old block of steel after
the Ark has been finished with a fine flat abrasive. Slurry from
another hone might be a good choice to give the steel block a
bit of action. The slurry bits will break down and ultimately polish
more than abrade.
Old block of steel... use a Gold Dollar if you have one in the box ;-)
Once conditioned and polished it is good for decades. Yes use oil,
or WD40. I thought I hated mine until I learned this.
