Thread: Hone of the Day

This came in today. A 6/8 Romo by Prior Solingen made for export for M.Mogal Inc New York.
It took a beautiful edge. I love how the butterscotch scales compliment the gold etching.

Just a bit of honing for fun.

G Johnson.
Formed a bevel on the Naniwa 800k
Set the bevel and fine tuned it on the Debado 1k
Full Nagura progression on the Nakayama.

It was a pleasure...apart from the heel that didn't want to cooperate

The Morley & Sons razor I have been using is starting to taper off. Not tugging or pulling, but giving my chin pimples and giving a weeper when I shave. Unfortunately that means 25ish shave are the limit for me for now on a thuri edge.

Time to try to see how long until a coti edge gives me those issues. Touched up this Koken Army and Navy razor, starting Naniwa 5k & 8k then this troublesome coti.

A little story on this hone. It is my first coti, probably bought 5 or 6 years ago. It has always been the most touchy stone. You go too hard and one little grain would put dings in the edge, destroying the bevel in one spot. I tried concaving the stone as others have done and didn't like it, but got rid of the troublesome spot. Reflattened it and resurfaced in my standard fashion. Sandpaper to 1000grit or better, then gently smooth the surface with a slurry stone under running water.

Finished the edge with 200ish water only laps, rinsing the stone every 20ish laps and keeping it well watered.

Stropping done on my Kanayama 30k, 100 linen and 150 leather. Shpuld have gone 150 linen/200 leather, but it was late.

How are you guys lapping Quartzite or Jasper. I picked up an oblong 2.5X1.5 slice of Jasper, or they said was Jasper?

I tried it on some edges and it just scratched the bevel.

What is best to lap and how high should I lap or polish?

Marty, just gadflying here, no real experience, but super hard quartzite stones, like hard Arks seem to be basically ‘micro files’. It isn’t the grit in them doing the cutting, as with a slurrying stone, it’s the surface texture.

Barber hones share a similar trait, they’re not that fine, but the flattening and smoothing of the grain makes them work. Lap them and you start over.

I believe you are right, Steve. Especially about the super hard arkies.

Hope this helps--

4 nice razors finished today, for one of our UK members, I'll be posting them back out later, no issues all of them were a doddle to hone, pins also tightened job done.

I have several quartzites and a few jaspers. Treat them like an Arkie. Flatten both sides, after flattening, use w/d up to 1000 or 1500 on one side then start taking steel to it for burnishing. Sand the other side to 220 and use a diamond plate to slurry, it will be a fast cutter.

They work best for me with oil or glycerin cut with water, water only on the slurry side and if oil is used, I wash with Dawn.

Would love to see some pics of your jasper.

Front row left to right: Sioux Quartzite, Maroon Sioux Quartzite and unknown green quartzite.
Back row: Owyhee jasper and petrified coral. The coral was a failed experiment and will trash an edge in a heartbeat.
