3M | PERFLINE

Knifeless tape can be used to cut vinyl without a knife. The tape is extremely flexible and turns smoothly in any direction, conforming to even the tightest contours and edges of any surface it is applied to.
Features:

• A narrow, flexible adhesive tape with a strong fine filament attached to the adhesive side
• The filament cuts when pulled outward through the material that’s been applied over the tape
• Eliminates accidental surface damage from knives to automotive glass and exterior paint finishes
• Used to cut vinyl between wide gaps between doors, seams and rubber seals
