Am I the first person to ever pick one of these up? I made a post a while back on the other forum about regrinding the profile to flatten it out a bit, so here are the results of this. Let me just tell you that it took forever to do by hand on my DMT XXC/XC it took 3 separate occasions and I decided to give up and just use it as is, but found that I really like it like this. I always thought I would be a cleaver guy, but realized that I like thinner more nimble knives instead. However, the Kagayaki still appealed to me because I didn’t like the tall blade so much of my Suien, and kind of wanted a go-between of a nakiri and cleaver without losing blade length. Here is the before profile that I thought was too rounded for my tastes. Also a before size comparison to the regular-sized Suien VC. Now here is after about 2-3 hours of grinding at a really obtuse angle and even at times 90 degrees to the stone. The picture isn’t that great, but there is now a larger flat spot in the middle and it makes for much better cuts now. I was planning on selling Kagayaki before, but now I think I will hold onto it. The carbon steel doesn’t seem as pure as the Suien, but it also doesn’t seem as reactive as SK4 not sure what it is, but I would assume it would be better than CCK steel. It takes a great edge though and I’ve been enjoying playing around with it now that the profile suits me better. Just figured I would post this as no one has seemed to ever mention the JCK Kagayaki before in case anyone was interested in one.
