I got 270 blue#2 honyaki awhile ago but I haven't really had the chance to play with it too much.
It measures 48 at the heel and really nimble for a 270. The blade is crazy thin and probably even thinner than the 240 konosuke HD2 I had before.
The knife just glides through everything with minimal resistance, however, the food release is poor due to blade thinness and mirror polish.
Overall, I would buy it again in a heart beat and some one should really buy that 270 white#2.
