Fold a sheet of paper to a 90° angle, fold again for 45° and once more for 22,5°. Thats represents your honing angle on the stone.

Lock the angle in your wrist (very important, because your ability to maintain a constant angle defines your success) and hone on one side of the knife with circling or back-and-forth motions till you can feel a bur folding over at the other side. (Coticules give only very small burs, but it can be felt if your run your fingernail off the edge with a plucking motion.) It's OK to use some pressure while honing. Once the bur is present along the entire edge, turn over the blade and start honing on the other side (I find it easiest to turn over the handle, so I can keep honing in the same direction, instead of turning over the spine). Hone till the bur is present on the other side. Flip one last time and remove the bur with a few very light strokes.
Finalize with one very precise stroke at a slightly raised (obtuser) angle on each side of the knife.
No need to steel the knife (not off a Coticule)

Best regards,

My apologies for rezzing a thread here, but I recently bought a coti with the intent to use on kitchen knives (and razors, if I ever need to). I'm yet to have a need to rehone/touchup myself (my first few were done by honemeisters ofc) but I plan to use a barber hone/thuri for touch-ups, so the Coti is likely for maybe some experimentation and if I ever need to go back a step.

Anyways a few questions, if you guys don't mind:
  1. Do I need to worry about ruining the Coti with my kitchen knife? I currently have a VERY soft steel Chinese Chefs knife (4Cr13). The one I bought has a blue and yellow side so my idea was to reserve the blue for knives and yellow for razors.
  2. How would a yellow Coti fit in, in terms of progression with barber hone and a Thuri ("the genuine water hone"), not that I'd necessarily use all 3 in progression, but just curious.
  3. DMT325 is good to flatten these right?
  4. Is it just the same slurry stone for both sides? Don't need to worry about mismatching something for slurry stone?
