I tested my santokus, gyuyos, bunkas on some slices of turnip to see which ones required the least force to push through. The Teruyasu fujiwara knives were hands down the easiest cuts. The reason is the thinness behind the edge that makes them cut like light sabres. Add to that, the great feel in the hand, the nice broad blade, and great edge retention, and they're an absolute pleasure to use. The maboroshis work pretty much as well as the denkas, but the denka have a more symmetrical grin...
