Hasta La Ideas

Remember that elaborate Ixi Ruixin Pro knife-sharpening rig?

In contrast, look at how simple and elegant the design of this Tumbler Diamond Rolling Knife Sharpener is:

The magnetic block offers a 15-degree angle on one side, and a 20-degree on the other.

The rolling sharpener is also dual-sided: The continuous surface is diamond-plated, meant to do the initial sharpening. The spiral surface is stainless steel and meant for the final honing.

These go for $98—when they come back into stock. Due to high demand, Tumbler says, new orders won’t ship until December 16th.
