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. Slice's 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.
