What I would not want to do but to be right beside that fish monger and cut the same type fish with the same "size" knife.....just like one of the markets I went to in Old Italy this year.
Oh just to jump in and and practice some of the greatest arts of filleting a fish. To practice....Sashimi, an art, once he had finished the cut.
Hahaha I am thinking the same way too. But sword is for combat not for slicing a food. Well you can consider it a sword literally but since it was being used in food so it's called knives. I like the way he cut, he got a very fantastic cutting skills.
