I had the first thinning session for a JCK Fu Rin Ka Zan W1 petty. http://japanesechefsknife.com/Furink...eSteel#1Series
Started with King1000 stone and after a while swithced to King6000.
These are pics after ~5min of work with King1000:
What is happening here? Why does it turn into blunt grey? Is it drawing material from the Nashiji finished Hira, which then sticks to the part between Shinogi and Hagane, or what?
It originally looked like at JCK website; shiny metal colour with deep grinding scratches.
Here are pics after ~15min with King6000:
(I thought to move to safe side and continued with 6000 when I did not know what was happening...)
Firstly, is my understanding correct here:
1 = Hira, Nashiji finish
2 = Shinogi line
3 = Kireha, this part is stainless clad, or?
4 = "Hagane line"
5 = Hagane, White no1
Secondly, what should I do here?
- Take King1000 into action and give it a lot more work?
Would this cause part 3 (Kireha?) to lose its cladding and end up in situation where everything below Shinogi is just White no1?
How thick is the cladding in part 3?
Resulting in somewhat thinner knife would not be a problem, actually I would prefer it.
