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 or neoprene, for example. 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.

We have supplied thousands of shaped knives in standard and custom shapes for many types of cutting applications. These are available as KNIVES only or as KNIFE ASSEMBLIES (see below)
