“The specialist electric choice for 15° Asian-style edges — focused, fast and far less ambiguous than a one-size-fits-all sharpener.”

The Chef'sChoice Diamond Hone Model 316 is a two-stage electric sharpener built specifically around thin 15° edges. Fine diamond abrasive in the first stage hones the bevel, and ultra-fine diamond in the second polishes it.

Separate left and right slots mean contemporary double-bevel knives and selected traditional single-bevel Asian knives can be treated appropriately. It is a specialist 15° machine rather than a universal sharpener.

Lucy's Verdict

The specialist electric choice for 15° Asian-style edges — focused, fast and far less ambiguous than a one-size-fits-all sharpener.

Lucy · Head of Curation

Why we chose it

We chose Model 316 because it gives the growing Japanese end of our knife range its own maintenance solution. The two-stage fine/ultra-fine diamond system is designed around thin 15° blades rather than forcing them through Western geometry.

Who it's best for

Buy it if your core knives are contemporary Japanese-style 15° blades and you want guided electric sharpening.

Why Lucy recommends it

  • 2-stage electric; approx. 15° geometry; fine + ultra-fine diamond abrasives; separate left/right slots; for thin Asian-style edges.
