Thread: I used to hate Coticules

I got one of the bay a few weeks ago.

It's proving to be very nice. Fast on slurry, slow on water. Excellent finish.

1 7/8" x 7 1/4"

Wow great looking stones. Congrats.

hey Aerdvaark - this is a La Veinette, just purchased from Ardennes... for your reference. So new you can see that I haven't even lapped the corners yet!

Yep, that is a delicious La Veinette alright!! Super nice stone Butzy!!
No waves or grain, but sometimes like mine there are veins showing.
I have several La Veinette's now and three of them are fast on water too!

Iceni, is your coticule fast on water? What beautiful large stone!! Have fun with that lovely one!!

To me it feels pretty slow. Once you kill the last of the slurry there is a stage where the rock is on pure water but has a dull finish. It takes 50+ laps to bring the rock round from that to a point where the rock is taking a glaze. After finishing the rock is well glazed and gives reasonable light reflections. You can feel the surface change as you hone, It goes from sticky to glass like.

Stopping in the sticky phase gives very mellow edges, stopping at the glassy stage gives a sharper edge that is still smoother than any of my other rocks thuri's included so I've been taking it to that point with most of the razors I've honed on it.

There is also very little swarf without a slurry on it. On slurry it blackens in 10 laps.

I should have put this image up as well... Mines a bit of an oddball, It has a secondary BBW backing!

Hey, you can never have too much BBW!

I once melted one soaking in degreasing solution in a slow cooker.

Mine are labled Record La Port with a different logo. I will take a pic later today.

Mine read "Lapport Record Brocken" on the label. Was about 8"x 2" The fine side was a yellow/cream synthetic & the coarse was brown, probably SiC as it cut very fast.
They are still for sale but in smaller sizes now. https://www.amazon.de/LAPPORT-RECORD...LAPPORT+RECORD

I used to like coticules until I owned four. Don't get me wrong, I'm sure there are good ones out there, just happens that the first four I had were not good for me. However, I'm not an anti natural guy. My first two Japanese natural stones, an Ozuku Asagi and a Wakasa were brilliant. I shaved with the ozuku edge on a 7/8 Friodur this morning, had a three pass shave and at last I can say, I'm happy with naturals. Only worry is, I'm already looking for more....doh.

Hello

I do not totally agree with that "I do not totally agree with that" .

The label is german its OK but synthetic ?!

Put the water on the yellow side and see if the stone "drink water" Quickly or slowly ... hard to see on pics but i think its natural stone .
