Brass knives vs. Stainless knives

What's the difference?

 

Knives that cut using heat must be able to efficiently transfer the thermal energy from the heater core to the knife edge. Brass is the most efficient alloy for this purpose. However, being a relatively soft metal, brass will wear down faster than a harder metal such as stainless steel. Stainless steel does not transfer heat as well and must therefore be operated at a higher temperature to do the same work as a brass knife. This uses more energy and may shorten heater life.

Webcutter Hinges

Our hinges are one of the most important components of the Webcutter hot knife. They must allow free movement of the rotating knife without excess play for hundreds of thousands of cycles.
