The Slice 10512 Pen Cutter offers an alternative handle profile to Slice’s safety box cutter. Its slimmer cylindrical shape is ideal for hard-to-reach areas and it uses the same box cutter blades, offering the same great features. These include Slice’s proprietary finger-friendly edge that reduces injuries. Our pen cutter design limits the amount of exposed blade, further preventing accidental cuts. The blade retracts into its housing when the user releases the rubberized slider button.

  • Handle type: auto-retractable
  • Handle features rubberized slider button
  • Compatible blades: 10404, 10408
  • Finger-friendly edge stays sharp 11x longer
  • Non-sparking, non-conductive blade
  • Durable glass-filled nylon handle
  • Ambidextrous design
  • Rust-free blade
  • No-tool blade change
  • Lanyard hole keeps tool handy

    I still use this one to open boxes but prefer the smaller safety cutter that is not retractable.

    Love that it is auto-retractable. (Secret option to lock open is a life saver in some circumstances!!) It really is great for multiple uses. I tested this on several surfaces and it worked great.

More About The Slice Auto-Retractable Pen Cutter

What Is an Auto-Retractable Pen Cutter Used For?

The Slice pen cutter is used in much the same way as a box cutter or utility knife. It can handle materials as varied as fiberglass, clamshell packaging, and adhesive vinyl. Our auto-retractable pen cutter has a slimmer profile and different handle shape from our J-hook box cutters, so it is ideal for hard-to-reach areas that require more maneuverability. 

How is This Pen Cutter Different From a Slice Safety Box Cutter?

Our pen-style auto retractable safety knife offers the same utility as the safety box cutter, even using the same replacement blades, but the handle shape is different. Although our J-Hook retractable box cutter is the recipient of a Red Dot design award, not all applications lend themselves well to this kind of handle. Sometimes you need extra reach or a smaller diameter to get to the material you’re cutting. The Slice ceramic pen cutters offer another option to get the job done.

Why Buy a Box Cutter From Slice?

In a word: safety. You’re not just buying a box cutter, you’re buying a safe box cutter. Slice rethinks every aspect of design, from the blade exposure level to how to put a blade in a box cutter. Our proprietary grind creates an edge like no other that cuts materials effectively and resists cutting skin.

Keep in mind that many of our tools fit in the category of box cutter: pen cutters, utility knives and our J-hook box cutters. Each of these styles have an auto-retractable cutter option. The Slice pen cutter (auto-retractable) can cut to a depth of 11 mm, while our utility knives make cuts up to 22.36 mm deep.
