A bit baffling when you break it down. We always learned this was the "scissors throw" but the first kanji gives crab (as in sea creature) and the second something like clip or clamp?
What is the actual etymology behind this name? Does it refers to the crab's pincers? A special pair of scissors used to cut up crab?
Some insight would be appreciated.
(Now I'm hungry for steamed crab in garlic butter... shouldn't do this when supper is overdue...)
