Ugly is only skin deep?!

Hi Folks,
I was able to take my grandson antiquing this last weekend. Well; he, as every passenger for the last year, kicked over a junker, partially boxed, hone lying on the passenger side floor. He said what is this?? Well...I did not know!

Home again, I took the Whatzit beastly thing down to the laundry room and used a cut apart 80 grit sanding belt on a granite slab and tried to find out. I lapped the slightyl dished bottom to save time.

Well, it looked interesting! First lapping passes said Y?G Thuringian. Then.. and then.............

#1. When I lapped it with a 180 grit it looked fairly smooth.

#2. I thought after I lapped it with a 325 diamond plate , it 'twas worth a try with a Hard junker razor and it said that it was a 800 grit bevel setter and it did a great fast job!!

#3. Then I lapped it with a 1K grit diamond plate and ...I had a nice ~6k pre-finisher...and quickly!

#4. Well, I lapped it with an HGH and ... A final polisher, again quickly! To a shaving edge!

#5..................I am confused!!!!http://www.razorandstone.com/images/...s/confused.png

A heavy, fairly hard, mud hone; no smell, some 'almost cellophane' inclusions which break out as the little tan spots shown in the photo with no damage to an edge.

It was a carpenters hone as near as I can tell and it is now "George the Fourth!" Nameless!

Cheers

Any ideas as to what it is???
And what should I finally lap it to?

Does it slurry, if so what color?

How bout a pic of the side?

Whats the bottom look like?

Nice find!
A British "Grecian" stone maybe? Some of them are quite soft, fast prefinishers, and their slurry could be described as muddy. I would say Llyn Idwal, but they are usually harder. For lapping, I guess it's fine as it is.

White to light tan

First photo shows it, there are no stria that I can see, other than some very fine tan lines at an angle.
Whats the bottom look like?

You are looking at it!! I honed the bottom from a slight dish.
Odd one and does not match any of my other UK type hones. Not Charnley for sure nor Schwedenstein.
The UK has a huge amount of stone beds and so a stone may be almost anything.
Thanks!

I looked up the post about the "Grecian"
http://straightrazorpalace.com/hones...-uk-stone.html
It definitely is not a marbleized stone like the one shown.
Another post #1 looks a bit like it.

Charnly's that I have are bouts and thin slivers and not thick blocks.
Fun Geo quiz!
Hafta wait upon Niel or Hazicho.

Great when you're able to renew an object from the past!

Am I the only person who doesn't see pictures here?

Yes!!!

I also thought on a LI but i have to admit the pictures are not the best...

@richard:
Can you put up some more detail and daylight shots ? That would help

Hmm. Weird. Maybe because I'm using a mobile phone? I'll try taking a look on the computer later.

Tapatalk ? If so always curious things happen ;-)

That's a very interesting stone Richard. But sounds like it's a keeper. Looking forward to what some of the stone guys say.

OK works fine on the computer, guess it's a mobile thing. Not using TapaTalk though.

As for the stone, no idea what it is, but I've noticed in my own experimentations that certain natural stones will take on totally different characters if they are lapped differently. Some stones it makes as near as no difference, but some can be drastically different with a coarse lap vs. a fine lap. I've found that usually the finer lap is truer to the stone, and the very coarse laps will cut really fast for a short time but then start smoothing out.

Hi Richard,

really looks like an interesting stone. Definately no Escher type devonian age thruingian waterhone. If of german origin it looks like an ordovician stone. They typically do have those "flakes" in the stone matrix that appear while lapping the stone. But also some Lyn Idwalls have this (and others, normally hard stones especially the novaculite).
The interesting thing is your report on how the stones work. Actually I am researching some old german whetstone quarries with stones that can be used like coticules. Prepared with a thick slurry, you can set a bevel with them in relatively short time, than going through the whole progression by watering the slurry more and more and finally get the endfinishing with only water. Your description sounds like this hone you showed has comparable possibilities.

Well, can you make some more detailled photos of the surface of the stone. Are there any red or blue/black spots visible? How hard is the stone compared to typical coti and an ark?

Following is a photo showing the surface of some german ordovician whetstones that might have a somehow comparable look to yours?

Similar in hardness to a hard Coticule or common slate, not as hard as a "Dragon Tongue."

I have a llyn Idwal with similar flaking but it's pretty hard.

And I think his stone is the one closest to my hone. Hardness is in the fingers of the beholder!

Thanks Piet!!

I love mystery stones, I have couple of them, I never know for sure what they are. As for this stone I would say Llyn Idwal, from the dished side the stone was used on tools or knife. I have stones ,around 6k , and they leave a shave ready edge. Congratulation Richard, on whatever this stone isi
