Our verdict

A small cutter with a ceramic blade that retracts into a glass filled nylon handle. One material field says bamboo, which conflicts with the rest.

Overview

A ceramic blade extends from a glass filled nylon handle on this Slice cutter, and the handle retracts the blade by hand. The listing also notes a locking blade.

The reason to buy is a ceramic edge in a manual retractable design, which suits light cutting. The limit is detail: no replacement blade info and a confusing material entry.

Who it's for

Users cutting tape, film or cardboard who prefer a ceramic edge. The manual retraction cuts down on pocket accidents. Heavy trade work calls for a sturdier cutter.

Pros and cons

Pros
  • Ceramic blade material
  • Manual retractable handle
  • Locking blade listed
  • Light nylon handle
Cons
  • Material field says bamboo
  • Blade replacement not listed
  • Short blade for deep cuts

Performance notes

A ceramic edge stays sharp through light repeated cuts but can chip if it twists or hits hard material. The retracting handle covers the blade between uses. A short blade gives control, not reach.
