O-Oh Custom Knives

We occasionally make duplicate knives to get a better cost. 

We occasionally make custom knives that get cancelled before shipping.

We occasionally make mistakes.

​

No matter, our overflow is your bargain. Listed below are general dimensions of shaped knives that are in our O-Oh (overflow) inventory.

​

If any of these look like something you can use, please let us know by our referenced part number. These custom shapes can be mounted in many of our models, which we'll be glad to quote.


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.



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)

Shaped hot knife assemblies can be supplied to retrofit other models of the RX-80, RX-84, RX-75, and RX-90 models.
