Rouge du Salm backed boxed Coticule

Found this RDS backed Coticule for a good price so I picked it up. It was cool because it let me try two stones I did not have and wanted to try. I really liked it for mid range after bevel set as they are fast cutters. The RDS leaves a nice kasumi like finish on carbon steel knives. The coti fast too and was pleasantly surprised. It looks very even or homogeneous and was hard to lapp compared to my slurry stone. Way harder really. I did not lapp it fully as I could easily use what is flat for a while. I dont like to waste away anything I can use.Attachment 284876Attachment 284877

very nice looking coti, enjoy

I was reading over at razorlovestone, that the TDS can be used as a finisher. I know you said midrange, but have you tried by chance?

No I have not, but I think you are spot on. When I was honing I did say to myself damn this thing is a lot finer than I thought it would be. I just finished on the coti side but will experiment on finishing on the Rouge Du Salm.
One thing I did notice is the Rouge Du Salm left a nice kasumi finish on my higo and the coti not so nice. Good tip BWH1980 thank you!

You are welcome! I read about it yesterday morning I’m going to give it a go this weekend.

I purchased a Coti from another member of the forum. The Coti is backed by a purplish colored stone that appears to be a cross between a Belgian Blue and a Rouge de Salm. Since all three stones are mined in the same area, there may well be some seams that are part way between Blue and Rouge. The purple stone, whatever it is called, seems to be a decent prefinisher.

BTW I consider a Coti to be a prefinisher as well. I like honing on the Coti, but the edge is not keen enough to slice through my beard. So I finish on finer stones.

For see

Here its rouge du salm Attachment 286016

Hello viergedefer,
You have much more knowledge about these stone. Do you think it is RDS or is it a reddish bbw. Thanks for your response!
It also seems to be a pike made box. I have many old boxed Arkansas stones and they look very similar. As it is well made like the pike boxes. After Norton aquired Pike the box quality went downhill. Even the wood was not that good.

It depends always on the stone, the Layer where Rouge Du Salm is taken out also differs in its quality this means you can finde some very hard stones which seem not really to self slurry very well and there are very soft stones tending to self slurry. I also owned stones which where for sure Rouge Du Salm, just from the properties and from the look, but the slurry worked like it included quartz particles, this specific stone was very coarse or big grained, i compared it to a 3k equivalent.

Here is a Rouge Du Salm freshly mined or sold as „RDS“ directly from Ardennes. It shows the typical wine red coloration and slurry and is quite hard. It also shows orange spots which also appear on the vintage „La Lorraine“ stones. This does not self slurry....

Here is a comparison of Lorraine Rouge / Rouge Du Salm (RDS) besides BBW. The three on the left are Lorraine Rouge, the two right are BBW. You can see how reddish the coloration of RDS is compared to BBW.

Concerning fineness the one far left ist the finest Lorraine Rouge i ever came over. There is nearly no visible pattern, its like Looking on a synthethic pressed stone of very fine grain. Used with a lubricant like a light oil or water glycerine it polished like hell. So depending on the stone Lorraine Rouge / RDS can be a decent finisher. But is does not always have too....

Thank you doorsh,
Mine looks alot like the middle of the three you just posted. I would guesstimate it ar 4k-5k leaning twards the 5k. It leaves a finish like uchigamiri, nice kasumi finish. While the Coti side I would say 6k-7k, leaning to the 6k but it is a fast cutter. The Coti leaves a shinny finish and not so even, unlike the Rouge stone that leaves a very even finish. Thanks for your imput doorsh I appreciate it.
