Lưỡi dao

It took about five minutes to bring my dullest chef's knife back to a razor edge, and the rhino's weight keeps it steady on the counter while I work. The sleepy design is a fun little personality boost in my kitchen, but the real win is how effortless it makes that final sharpening pass.

The rhino's sleepy face makes me smile every time I reach for it, but it's genuinely tough on my bluntest blades. My chef's knife went from dragging through tomatoes to slicing them clean in one pass.

It takes up almost no counter space, which I appreciate in my tiny kitchen, and the rhino looks like it’s actually concentrating while it works. My dullest chef’s knife slices tomatoes like new after just a few passes through the slot.
