The wave-shaped serrations on this thing are no joke — it went through a crusty sourdough loaf without squishing the middle at all. Been using it daily for a couple weeks and it's still gliding like day one, no rust spots either.

I was skeptical about spending more on a knife, but slicing a ripe tomato used to crush it flat and now it goes through clean in one stroke. The ACUTO440 steel hasn't shown a single rust spot after weeks of hand washing, which I can't say for my old one.

The wave-shaped serrations on this thing are no joke — it cut through a ripe tomato without squishing it at all, which my old straight-edge knife never managed. Also nice that it's rust-proof, since I leave it in the sink way too often.
