I recently got both an Artifex 210 mm gyuto and a Konosuke HH 150 mm petty. I had the Artifex thinned out behind the edge before I got it.
The Artifex cut great. However, when I cut some veggies using the Konosuke, it cut even greater. I simply had a noticeable thinner blade. (The issue was not so much that the Artifex quickly wedged - I had it been thinned out - it simply had a thicker blade.) On the other hand, the size and height of the Artifex are much better for cutting most stuff.
Now my question is: does a Konosuke 210/240 mm gyuto have a similar thickness and profile as the Konosuke 150 mm petty? I that case I will at least consider a laser gyuto like the Konosuke (Gesshin Ginga, Suisin, ...)
