Thank you for sharing your experience with coticules Heirkb. Many of us here have been trying to pass this info on and one more voice in the chorus is welcome. Coticules are hones for experienced honing as you have discovered. Most honing techniques depend on observing the 'signs' of your progress. Thee signs are very subtle with coticules as a one hone method and are easily over looked by people new and experienced in honing. With Norton and Naniwa hones the signs are just a little more obvious. Good luck in your journey!
