Our verdict

An eight pack of small retractable cutters with a nine millimeter blade and a plastic and wood handle. The listing names a plastic blade, so they suit light cutting like paper and cartons.

Overview

Not a heavy steel work knife, this DIYSELF pack is eight small retractable cutters with a plastic and wood handle. A manual slide extends the nine millimeter blade, and the handles come in mixed colors.

A multi-pack means one cutter can live in each drawer, bag or craft box. The limitation is the plastic blade material in the listing, which points to light cutting, plus the absence of any replacement blade info.

Who it's for

Craft tables, classrooms and mail rooms that need several light cutters are the target. Contractors and warehouse crews cutting thick materials will want a steel-bladed utility knife.

Pros and cons

Pros
  • Eight cutters in one pack
  • Manual retractable handle
  • Small, easy to store
  • Mixed handle colors
Cons
  • Blade listed as plastic
  • Replacement blades not described
  • Not for heavy materials

Performance notes

Cutting depends on how sharp and rigid the blade stays, and a plastic blade limits it to thin materials. The manual slide sets the extension length and holds the blade at that setting.
