Overview
Not a heavy-duty utility knife, this bulk pack of red box cutters is for opening cartons and cutting paper and craft material. Each has a manual-retractable handle of wood and plastic.
A large pack stocks an office, classroom or shop with spares. The blade material is listed as plastic and the product style as automatic, which conflicts with the manual-retractable handle. Confirm the details before relying on them.
Who it's for
Offices, schools, craft groups and warehouses stocking many stations will use the quantity. Heavy-duty cutters should be chosen when cutting dense material.
Pros and cons
- Thirty cutters per pack
- Small blade for paper and card
- Retractable handle for safe storage
- Light and easy to hand out
- Blade material listing conflicts
- Style listed as automatic
- Lock details not given
Performance notes
A narrow short blade cuts paper, tape and thin cardboard but flexes on thick stock. The retractable handle covers the edge when idle. Replacement blades are not described.
