Expert Reviews

What reviewers liked

The Idahone stood out on a couple of fine details, too: Its ergonomic maple wood handle was more comfortable than the synthetic handles on the rest of the competitors, and its hanging ring is amply sized and sturdily made of steel.
They’ll remove some steel in the process of honing. Isn’t that technically sharpening? Yes! However, if you’re someone who doesn’t sharpen as often as you should, a ceramic honing rod is a way to delay the inevitable.

What reviewers didn't like

One of the only things we don’t like about the Idahone is the lack of a prominent finger guard where the rod meets the handle.
Ceramic honing rods are a bit more aggressive than steel versions. They’ll remove some steel in the process of honing.
