#10 Knife Stone from the Nakayama mine
This is an asagi tomae with faint Kan or circular pattern on the straight left side. It will hone razors to shave ready, but the shape suggests that it would feel more comfortable working on knives. A tested tomono nagura slurry stone will be included.
196 x 71 x 23mm thick
with out the wooden base it should weigh about 800 grams.
The wooden dai is just fine and it will fit into most stone holder, trying to remove the base is usually more work than is worth it.
#10 Nakayama Knife size and shape Stone
All of my stones are sold with a money-back guarantee minus the return shipping if within 30 days of the sale and returned in their original state. Please do not lacquer the stone if you have any intention of returning it.
I encourage sealing the sides of all sedimentary stones, especially if there a inclusions, cracks, or fissures and or if the stone is used in an active workshop where the stone is constantly wet. For casual use, sealing, especially all four sides, and preferably the back with one of either a marine type of spar varnish, a synthetic lacquer, urushi, or a cashew-derived lacquer is prudent.
How I am able to guarantee stones
Not all sharpening stones will sharpen steel fine enough to shave from the resulting edge. Many are fine for tools or knives, and I test for those uses as well. In my testing I first create a fresh bevel on the chosen razor with a 1,000 grit King red brick stone. With the new bevel at the razors edge formed I next use a well-worn Atoma #400 diamond plate to raise a slurry upon the test stone, and it is this slurry and only this slurry that I use for honing the test steel.
If the razor's steel bevel, with a 1k King scratch pattern can be honed by that test stone to a shave ready after a simple stropping in:10 strokes = extraordinary: 20 strokes = noteworthy: 40 strokes = worthy, Any more than that I make a note and try a different steel.
Stainless, high carbon, wrought iron, all can be tested and noted. Matching stone to steel saves time in the long run. This is why chisels come in sets, and bullet calibers exist. Efficiency cannot be faked when sharpening razors. Adding muscle or weigh flexes the blade leading to irregular wear patterns on the steel. Drinking whiskey to pass the time while honing razors for more than 10 minutes suggestes, well, a waste of time.
