Thread: Vulcan stone

Has anybody ever used a Vulcan sharpening stone? They look like a Coticule, but they are from Germany.

Never heard of it. It does look like a coticule though. Not a bad price for a stone if it performs well.

Those stones are very slow stones. You can try to prep they surface and they will kind of get more polished/smooth.

Its a finishing stone and should be used after a 8k or 10k. Very slow stones and in the finishing stage the usage of oil or water glycerine is preferred over the usage of water.

Final polishing result is very good, i personally wasnt fully convinced on the shave itself, which is actually more a personal issue because i like my edges very smooth. The edges i got there were more sharp, a little bitting....

Some more information here:
Abziehsteine - »KIRSCHEN« Werkzeuge
It does not give more information on the yellow side other than the recommendation to use it with oil. They say the slate backing can be used as a coarse sharpener, to be used with water. They sell coticules as well so if it were a coticule I guess they would mention that.
English translation of their website is not unfortunately not very good.
Hopefully Peter or Sebastian will chime in. They both have studied German sharpening stones in detail.

Sebastian (Sharpchef) did a Review on the GRF, check Post 131, sure its in german....

There are more pictures where you can see how the stones look, they are harder then Coticules...

Might they be reconstituted Coticule stones with a resin binder?

Record had some of those stones years ago. Record Lapport.

Would it make sense to use these in a progression where a C12K is the final hone?

Depending on what hones you have, it's probably better to pick one or the other as your final finishing stone. If you're coming off an 8K or 10K stone you really don't need anything to bridge the gap between your final synthetic and (most) natural hones. My Cnat is between 8K and 12K, adding in a natural between the Cnat and my 8K stone would just be adding time to the process with no real benefit to the outcome.
