Idahone CS-24 V-Type Ceramic Rod Knife Sharpener with Hand Guard

The Idahone CS-24 is for cooks who want guided, repeatable sharpening with an added measure of protection for the hand steadying the base. Its solid oak base holds the ceramic rods at fixed angles, so the user keeps the blade upright and draws it down the rods while the base controls the bevel. The included hand guard sits between the rods and the hand holding the base, which makes the CS-24 a sensible choice for a household where several people sharpen their own knives.

What It Does for Your Knives

• Hand guard: Shields the steadying hand from the blade during each stroke.


• Two angle settings: One setting suits the narrower bevels of Asian knives, the other the sturdier bevels of Western knives, so a mixed knife block can be sharpened on one tool.


• Coarse and fine rods: The coarse pair restores a dull edge and the fine pair refines it, covering both sharpening and routine touch-ups.


• Vertical technique: Holding a blade straight up and down is easier to repeat than holding a set angle against a stone, which produces a more consistent edge for less experienced sharpeners.

Choosing Between the CS-24 and CS-4

The Idahone CS-4 V-Type Ceramic Rod Knife Sharpener is the same sharpener without the hand guard, for cooks comfortable working without one. Worn or broken rods for either model can be replaced with Idahone coarse replacement rods or Idahone fine replacement rods.
