I did this knife and his spyderco endura 4 for a gentleman in the USCG the addict was on the house but I charged 10 for the spyderco plus shipping. Usually I don't charge military but I had 3 hrs at least in the addict and an hr in the spyderco, he tried to make his own bevels on the vg10 spyderco and it took a while to straighten it out. Should I feel bad about charging military. I used a m5 shapton I bought from olpappy and I liked that stone I now Japanese woodworker sells the and they have 2 other kinds besides the pro and m5 no gs does any body know anything those? Peace to all, jmbullman. Btw Shaun Fernandez I o u big time for that tip with the 120 gs it works great.

No problem, I know how I was slightly disappointed with the Shapton 120 and 220 at first also. Once you raise a slurry it's another ball game! Lightning fast.
Hey there, to keep things on topic, how's about we make a separate thread for posting about edges we've achieved and the progression we used to get there! I'll get the ball rolling, let's show off our goods!!

Not to be pedantic, but slurry is a loose term for any knife of wet-ish semi-colloid. Cornstarch and water, for instance. Swarf refers exclusively to metal debris, even that dry powder that comes off a grinding belt. The stuff from the stone that isn't Swarf is often called "mud", which is literally correct for Natural stones, but helps to differentiate between the two even on synthetics.
I always use "slurry" when sharpening to refer to the mixture of mud and swarf and water.

"Swarf can increase the polishing effects of a stone, BUT it does not increase the cutting speed of a sharpening stone. "
Well not always.
I did an interesting experiment a while back. I have two knives - a Spyderco 'Mule' made of solid Aogami Super and a Kitchen knife also made of Aogami Super but clad with a softer steel. I noticed that I was getting negligible sharpening effect on the Spyderco (I forget what stone it was, perhaps a natural). It seemed puzzling to me. I tried the same stone on the clad knife and had good effect. Without removing the mud which contained the steel swarf from the clad knife, I again tried the solid Aogami super and got good results.
So the soft steel or cladding swarf component of the slurry was a key component of the slurry to produce the desired effect. I'm not quite sure if the swarf component enhances stone breakdown rates on naturals or not. Pure swarf or metal powder is used by sword polishers for final finishing effects. This is referred to as nigui and is sometimes produced as a byproduct of sword making. I believe this is the firescale from the forging process, finely ground as a powder and made into a paste with some clove oil.
With natural stones - especially the Japanese ones - it's ALL about properly developing the slurry.

Well said ken well said. Does anyone out their believe the yagonoshima is one of if not the best finishing stones out their on carbon or are their better? Do tell. Peace jmbullman

So are you saying that cladding is what changed the stone, or just swarf?
