Donic Persson Powerplay. 7-ply all-wood blade with total thickness of only 5.9 mm. It has koto outer ply. But the handle is regular. I will not consider it small or thin, but average.
Avalox P500. 5 ply all-wood blade with total thickness of 5.7 mm. It has koto outer ply. Again, the handle is regular. I will not consider it thin.
Same composition with Avalox P500 is ITC Dynarc T5. Koto (burned or thermal treatment) outer ply. Again, handle is regular.
