Product Details
Product Details +

A manual rolling knife sharpener with two sharpening stages, a diamond-coated roller for fast edge restoration and a ceramic disc for fine honing. A magnetic angle guide clips onto the blade and locks it at a fixed angle every pass, 15 degrees for fine edges or 20 degrees for sturdier ones. The rolling mechanism draws the blade across the surface in even, controlled passes, so there is no rocking, guessing, or freehand angle holding.

Key Features:

  • Diamond roller sharpens, ceramic disc polishes, both in one tool
  • Magnetic angle guide locks the blade at 15 or 20 degrees every pass
  • Non-slip base, rolling mechanism, no experience needed
  • Stage 1 reshapes the edge, stage 2 refines it to a clean finish
  • Use both stages for a full sharpen, or stage 2 for a quick touch-up

Specifications

  • Stage 1: #400 diamond roller
  • Stage 2: #1000 ceramic disc
  • Angles: 15 degrees (fine) or 20 degrees (sturdier)
  • Compatibility: straight-edge kitchen knives only, not serrated
  • Colors: Brown, Black
  • Includes: 1x Rolling Knife Sharpener, 1x Magnetic angle guide

Materials and Care:

  • Wipe sharpening surfaces clean after each use
  • Do not submerge in water

Frequently Asked Questions

Does it work on serrated knives? +

No. The rolling mechanism and angle guide are designed for straight-edge kitchen knives only. Serrated blades require a different type of sharpener.

What is the difference between 15 and 20 degrees? +

15 degrees creates a thinner, sharper edge for precision slicing (Japanese-style knives). 20 degrees creates a sturdier, more durable edge for general kitchen use (Western chef knives).

Do both stages need to be used every time? +

Not necessarily. Use both stages for a full sharpen on a dull knife. Use stage 2 (ceramic) alone for a quick touch-up between full sharpening sessions.

Is it difficult to use? +

No. Attach the magnetic angle guide to the blade, set the angle, and roll the knife across the sharpening surface. The guide holds the angle. The rolling mechanism keeps the motion smooth. No experience needed.

Does it slide on the counter? +

No. The non-slip S-pads and silicone feet grip the countertop and keep the unit stationary during use.

How often should knives be sharpened? +

It depends on use. A frequently used kitchen knife benefits from a full diamond and ceramic sharpen every few weeks, with ceramic touch-ups in between.

How long does shipping typically take? +

Orders are processed within 1–2 business days, and delivery typically arrives in 7–10 business days. Tracking information is provided once your order ships so you can follow its progress every step of the way.

Please read our Shipping Policy for more information.

What if this isn't right for me? What's the return policy? +

Every TENAX product is backed by a 30-day return policy, giving the opportunity to try it and ensure it meets expectations. If it doesn’t feel like the right fit, returns are available within 30 days of delivery in accordance with the return guidelines.
