Received my Kohetsu HAP40 240mm about three weeks ago, and though generally happy with it so far, I felt the edge should have been a little better than the way it came OOB.
A week ago I gingerly tried to improve it on a Chosera 5k, but results were unsatisfactory. The edge felt as if it was skating on the stone, and I gave up as I was tired and slightly the worse for wear after a few drinkies.
This morning, well slept and alcohol free for a week, I decided to have another go, but this time starting on a Shapton Pro 1k.
This gave big improvements, and despite my understanding that these are not 'mud' stones, I had even better results after loosening up the surface with a few strokes of a DMT 10" Coarse plate and NOT rinsing off the 'paste'. Twenty minutes of slow, careful strokes - less on the left side, as the bevel seems to be 80/20 - and I was ready to progress to the Cho 5k again.
This time the stone worked well at polishing out the 1k finish, so I decided to use my balsa strop and 1um diamond spray for the first time. A dozen light strokes on each side, followed by half a dozen on the horses ass, and I have a lethal, razor-edged slicing demon!
I decided to skip the 'snow-white' 8k, and it certainly seems unnecessary considering the result achieved.
with all CKTG products so far, and enjoying the learning curve.
Any thoughts on my progression? As a relative noob, expert advice will be appreciated.
