Getting ready to try some slurry finishes with the new lighter eNat stone so I did a quick test with the HSS test piece on the convex bevels to compare the slurry finish from the eNat stone to my...

Here are some shots of my HSS (High Speed Steel) test piece convex bevels from the eNat. The area immediately behind the bevel is a near mirror finish from a very hard and fine JNat. The first two...

I think this stone may be a variety of quartzite, BTW if anyone's interested. Mostly composed of silica.

Here are a few more scope shots showing a prefinish on an 8k then ~30 strokes with 1 layer of tape on the natural stone at various points along the edge. Very nice looking edge.

Here are some microscope shots from Slice of Life showing first an 8k edge just starting to be refined by the stone, then after some more honing showing the sharpening of the edge of the edge...

Here's some test results from Alex Gilmore with his 600x microscope, pretty darn cool, wish I had one of those babies. It would appear that his results are similar to mine, in that this stone can put...

I did a quick freehand sharpening on a chisel today with this stone, turned out pretty nice. The photo highlighting the scratch pattern is lit with 450W of fluorescent lighting at just the right...

Lol, there's no mountain, these rocks were probably deposited as till by a glacier near Lake Michigan a very long time ago. The lake they were found near is a type of lake called a kettle lake IIRC....

I'm just experimenting with this, but I'll say this much: the edge finished on a slurry shaved quite well.

And here are the most magnified shots I can get showing the test piece finish through my 30x optical microscope.

Shaved with the edges, and actually found them pretty comparable. I think the new stone is a little smoother.

On another note, I've done a little more slurry testing tonight and got some...

Tried a slurry honing but wasn't happy with it. I was easily able to shave with it but wasn't as smooth as the oil finish. Just freshly honed two razors from bevel set. Both progressions started the...

The stone does not float.

Lol, yes of course it's heat treated. It would be kind of pointless otherwise. The item in question is a contact point for a dial indicator made by a company called Starrett. It can only just be...

Here are some photos of some more trials today with slurry on water. You can see with the slurry it finishes up as a hazy mirror. I finished this test piece with figure eights. Really a neat stone,...

K just had a nice full shave after letting my face rest for a few days. OUTSTANDING shave. WTG was really probably the closest WTG I've ever had, and ATG for no irritation whatsoever and BBS. The...

Lol. Not sure how you'd find out the indigenous people for a glacial stone - it could've come from anywhere I'd think.

I'm actually sending a sample stone to someone pretty well known to get...

I just tried taking a rubbing stone and lapped the hone and the rubbing stone both with the 400 Atoma then used the rubbing stone to smooth the surface of the hone. Slapped on the 2 layers of tape...

Don't have any of those, but I can probably get some muriatic acid from where I used to work - think they have a jug. I've also read that some limestones need to be crushed to show much reactivity,...

Uh. Yeah. Anyway, tried the vinegar after reading that it should bubble if it's limestone - no dice, the vinegar just sat on top of the stone like water. Same with oxalic acid paste.

Can you give me further info on testing? I would like to discover what the heck this is for sure. I figure it is at least 6 Mohs if it cuts hardened steel, right? What sort of acid would I need? I...

Here's a quick test I did on a knife - the sides of the knife started out with a pretty dull finish from a DMT 320 plate, so I didn't expect to see much of a difference in finish since this is a...

Heh, must be a running joke that ran right past me!

One more data point, the stone can be broken away by hand if there's a thin sharp edge (I guess most any rock can), but when it's thick and...

New natural stone I'm trying out - found this near a glacial lake and decided to give it a try. Looks like a sort of layered sedimentary type of stone, and it slurries up pretty quick with an Atoma...
