RX-80 Shaped Hot Knives & Hot Knives for Cutting Ribbon
These models are designed for cutting shaped ends into ribbon, webbing, slings, hook & loop, and other synthetics fabrics and materials. Shaped hot knives will cut and seal the ends into Standard or Custom shapes. Six standard knife shape types include: half round, V-shaped, bullet-nose, beveled, rounded corner, and tactical. Custom shapes can also be made to your specifications and are about 10% to 15% more expensive. All our knives are manufactured from either highly conductive brass alloy, or long-lasting stainless steel.
MATERIALS NOTICE: Most of these machines use thermal tooling made of brass alloy and cannot be used with materials that contain any PVC. Please contact us for alternate tooling options.

Replaceable Standard & Custom Shaped Knives
Replaceable hot knives are an option when knife wear requires, or if a different shape is needed. Replaceable knives can be precision machined from either stainless steel or brass plate.
When replacing these knives, it's a good idea to clean the back of the knife and the surface of the heater block with very fine sandpaper to ensure efficient thermal contact.
