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

    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.

    A while back I had similar problems with a convex LVRR coticule bout that I was playing with. When I would slurry the stone it would shed particles, leaving small voids in the stone. It was and still is an aggressive stone but the resulting texture was unacceptable to me. I lightly retextured it with a diamond plate and started over.... with the same results. The stone was put away for a few months in frustration.
    A bit later it was revisited with a different mindset. Without slurry, I honed three different knives on this stone over about a month's time. The coti started to show a burnished looking shine and much improved surface texture. Due to the aggressive nature of this particular stone I now use it without a slurry stone for pre-finish work.
    I am not implying that this is the problem with your coti, just that these wild caught hones can sometimes refuse to fall neatly within the parameters we humans tend to set.

    I have had a couple Globusmen Golds in 6/8 over the years. Sold them because they were not mint enough, which is the difficulty with these. Yours looks pristine, enjoy it good health.

    Cheers, I brought this one a few years ago, looked NOS to me. It's a 5/8 that I got for the price of a Dovo "Best Quality" I think the smaller blades get overlooked for the big uns.

    Just honed this W&B up from scratch..
    Established a bevel on the Naniwa 800k, then set the bevel on the Debado 1k, then a full progression on the Ozuku finishing with water strokes.

    It was an accomplishment to get the bevel set from heel to toe at the same time..I nearly got the green brick out but i'm glad i didn't do that..

    HHT was not happening until i turned that hair around, ping ,ping, ping..OK it was silent but you know what i mean..
    Cheers..

    Joseph-I'm just curious what you have against the green brick. Saying that, I have no experience with the Nani 800 or Debado 1k; you may have a better system.

    So because I can't help myself, I further refined the surface and radiused edges of my new Dan's primitive 14"x4" with 2k and then finished on 3k. You can't tell it from my lousy pic, but looked at obliquely lengthwise, it is glass smooth. After a couple of kitchen knives, I took the Fox Cutlery 142 (an early rescale of mine in Gaboon ebony) that was just too sharp on the last shave, and gave it a spin. It cut effortlessly, but left me very raw. I couldn't tell you how I honed it because it was years ago-it felt like an edge overcooked on a high-grit synthetic (maybe Ron/Utopian's SG20).

    So a few squirts of WD-40 on a very hot hone that had been drying on my sunny deck rail, and that heat-thinned WD-40 was just sheer joy to do full-length "windshield wiper" laps on to smooth it out-I think I've invented a new technique-hot honing! Of course the test shave will see how much I smoothed it, but it still feels extremely sharp. And the feedback on such a hard, smooth stone is just silky smooth-I could feel it getting smoother.
