took, a blade that is beveled on both sides, if not cutting straight
down through something, will tend to twist toward a more horizontal
position, making it difficult to make an angled slice that removes a
piece of constant thickness, which is important when making sushi.
Using a blade with a single bevel, and held with that bevel on the
upper side, lets the blade make a straight cut through the object
without twisting. How recent that attention to detail is -- or, at
least, that _explanation_ of what it is for -- I don't know.
