A couple days ago, I was in T&T, a large urban Canadian, Asian chain. I was near the fish area and heard this very loud and repetitive pounding. I walked to the counter and watched. He was using a cleaver/chopper in conjunction with a mallet (rubber on the outside). He was chopping a large fish, into 3 to 4 inch sizes (steaks)?.
- light slice
-pound the spine of the cleaver/chopper with the mallet.
