I had to look this one up too because honestly, the title 'Sashimi Knife' doesn't exactly give much away, right? From what I pieced together from a few forum posts and the synopsis on some Korean sites, it's this wild action-thriller about a guy whose family gets caught up in some ancient, bloody conflict over a legendary knife used in a... sacred food ritual? Or something? The main character seems to be an ordinary chef or student who inherits this knife, and suddenly he's being hunted by shadowy clans who believe it holds some immense power. The plot basically revolves around him trying to survive and uncover the knife's true history while these assassins come after him.
It sounds like a very specific blend of culinary culture and brutal, almost supernatural martial arts. I haven't read it myself, but the descriptions make it seem incredibly violent and stylish, like a Korean take on a John Wick movie but with more focus on blade techniques and kitchen tools. Apparently, the art is supposed to be super detailed, especially in the action panels. Makes me wonder if the author has a background in cooking or weaponry.
