I would expect that a brand new knife set would never again be as sharp as the day I open the box. Tested these beside my old one and it didn't do any better. You'de expect "Sushi" knives to be dreadfully sharp. I could even cut myself on what I received. They are beautiful to look at, have a good weight and appear to be made very well. I even like the way the indentions on the side stop the slices from sticking to the blade, but...l and this is a big BUT these knives aren't very sharp and I do not believe I could in fact cut sushi with them. It's a shame! I'm glad they were hugely discounted! I'd be angry if I had paid full price and would return them! As it is, they were very inexpensive and worth what I paid, just expect to have to sharpen them yourself when they arrive!
