Which is the profile that you have been using up to this point?
As I've said many times before, it's the best all-round profile that I've used. It's an excellent balance between all of the different cutting motions that someone may make with a gyuto and fits very well with the rest of the knife's characteristics which makes it the most gyutoy gyuto. The board contact is really astounding and it's very easy to make complete cuts no matter what part of the edge you cut with. There's never the "clunk" sensation and the "sweet spots" are so large that the entire edge is useful and a pleasure to cut with.
It's very obviously a profile that's been designed by someone who's seen many tens of thousands of knives, spent a lot of time actually LOOKING at them, and got feedback from people that actually knew what they where talking about.
The flatter profile is the one I've been using all along. I'm happy to hear that you like it and I thank you for the feedback Justin.
