Overview
A pull-through knife sharpener from AccuSharp with reversible diamond-honed tungsten carbide blades, an ergonomic handle and a full-length finger guard, made for both straight and serrated kitchen knives.
The sharpening blades are tungsten carbide rather than a stone or ceramic rod, and AccuSharp designed them to be reversible so flipping them roughly doubles the usable life before replacement. The handle is shaped for either hand, and the guard runs the full length of the sharpening slot to keep fingers clear of the blade during use. AccuSharp reports most users go 5 to 10 years between blade replacements.
- Diamond-honed tungsten carbide sharpening blades
- Reversible blades for extended life
- Works on straight and serrated edges
- Ergonomic handle with full-length finger guard
Who it's for
Works for anyone maintaining chef's knives, paring knives, fillet knives, cleavers or serrated blades who wants a quick pull-through touch-up rather than a whetstone routine. Not the choice for someone chasing a fine polished edge or precise angle control, which a whetstone or guided system handles better than a pull-through sharpener.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sharpens most blades in about ten seconds
- Works on straight and serrated knives
- Reversible carbide blades extend usable life
- Dishwasher safe, ergonomic handle for either hand
- Removes metal rather than honing, so it is less precise than a whetstone
- Not built for fine edge control on specialty blades
Performance notes
Pulling the blade through the slot works by removing a thin layer of metal with the tungsten carbide edges rather than honing the existing edge the way a steel rod does, which is why it restores a dull blade quickly but does not offer the angle control of a whetstone. The double bevel and reversible blade design mean both sharpening edges see wear evenly, which is what stretches the years between replacements.
