Brian's guide to the galaxy (Japanese chisels)

They are called coticule - I think the spelling is correct - and its a very good stone but you must make one major distinction when going on and on about them and that distinction - David Weaver (whoever he is) would have to agree - is between the old solid chunks and the new laminated. The coticule is made up of a double stone layer. The cream color is the cutting stone, the blue/purple layer supports this. Well, presently due to the great depletion of the strains the double stone as a single unit are rare, to compensate the cream and the blue are mined separately, machined and then glued together. Of course this diverts from the topic at hand so I keep in short and simple this way.

Brian, good info on this subject.
Do you have any experience with Belgische Brochen or Belgian chuncks which are more common in europe ?

We have one at work and its a fantastic stone, they certainly dont have their reputation for nothing, cuts faster then a stone that fine has any right to and leaves a Mirror Finish. Though it being a Natural stone none are really alike so experiences probably differ, the one we have is an unlaminated solid Yellow/Cream one. Those are almost impossible to get nowadays and if they are seriously expensive.

Yes a real shame that they are depleted, the yellow is a great stone. However there are still sizeable Chunks of the Blue one at agreeable prices, they are said to be similar if a bit less agressive and harder stones. I cant really comment though since i've never used one though from all i heard they are supposedly pretty nice.

To bad this is completely off the topic because it's a fun topic itself.

Hmm, I vaguely remember there being something you can do about that... it'll come to me... oh yeah, start a thread.
