Thread: Chamfering the edges on a Coti

Just a quick question guys.

I have been warned not to use a diamond plate on an Ark or any slate.

Can I use a diamond plate to chamfer the edges on my coti?

Well I've always used a diamond plate on all of my coticules to do so... But I might been wrong ?

Some are against using the diamond plate on natural stones to raise slurry ... But using it on the edges to smooth them does not create any problems anyway.

Sure, just make sure you run your slurry stone around the perimiter afterwards a little to kill any roughness from the dmt finish.

I chamfered the edges on my new Coti, I also did my small slurry stone as well. I know I didn't need to but I thought I might as well while my 400 diamond plate was out.

I played with the stone yesterday and achieved absolutely nothing so I did a bit more research this morning, one thing that was made clear is not to allow the slurry to dry while your using it.

Oops. I decided to try the unicot method suggested on the coticule site. I didn't expect to get anywhere as I only got the stone yesterday but I am speechless.

That method must be foolproof for anyone new to a coti.

I used a kinfolks full hollow and it tree tops as well as any razor in my stable. I will shave with it in the morning and really hope I won't be dissapointed.

I bought a Boker from Badgister with a coti edge, it is so smooth that I decided to get the coti. I have only used it twice so far so I will use it as a yardstick for my own coti edges, I would be so pleased if I could make all my razors as keen but smooth as that Boker.

I killed the edge on my Kinfolks and used the coti as a one stone hone from bevel set to finish as the Unicot method suggests.

Yeah, letting slurry go dry or overly muddy is bad news

yes you can

Now this is a rabbit hole you are really going to enjoy exploring.

Did Ardenes give you any hint about the vein from which the coti came? If they did, they have opened the door to another rabbit hole that focuses on the various layers from which the stone was mined.

They said they hadn't named it but it is select. It's newly mined not vintage.

I can get special stones like La Vienette or La Latneusse (don't know how to spell that one) but they are expensive and I need more rocks, lotsa rocks

OMG - what happened, I can't stop looking longingly at stones. Have you seen the Ancient Sea Jasper - Purty!

Unicot with the use of tape for creating a micro-bevel is indeed a highly effective way to finish a razor.


I modified it a bit to suit my preference and ease of use.

If I want to know how well my Coticule finishes, I just hone up my razors as usual or take an already shave ready edge, add a layer of tape and finish under running water. This always works really well.

In comparison I find my 20K and Coticule edges to be both very smooth.
About as keen, perhaps a slight advantage to the 20K;
but the Coticule edge is skin friendlier and more forgiving when finished under running water.


What I usually do with razors that aren't too far off, is hone them on the Coticule and BBW dry.
Coticule for the quicker and rougher work to make sure the bevel is set entirely and the BBW for refining and polishing the edge. Most time is certainly spend on the BBW this way for me.
I personally found this the easiest and fastest way to SMOOTH out any imperfections while create a super sharp edge.

If the bevel is too far off I resort to a Coticule with slurry, but I always refine on the Coti and BBW dry.

Honing dry gives me excellent feedback as well, I can easily tell which parts of my edge are smooth and which ones need more work.

I take a piece of folded over toilet paper and cut through it to feel for imperfections left in the edge, as long as there are I keep honing on the BBW dry until they're gone.
The edge coming off the BBW dry is always amazing. It's a super sharp shaving edge, but can use a little smoothing out for my personal taste. [Using them dry makes me forgo/replace the dilution steps with slurry, which I personally do not enjoy much.]

After refining on a BBW dry, I add a layer of tape and finish on the Coticule under running water.


Whatever gets you a superb shaving edge is all that matters!
Enjoy honing on your Coticule, I greatly enjoy mine.
