  • 105 watts Hot Knife Foam Cutter

  • Transformer-Powered Hot  Knife

  • Heats Up Hot Knife Blades in Seconds

  • Lightweight -- Only 1 Pound

  • High-Quality Hot Knife Blades

We've packed a whopping 105 watts of power right in the handle, making this the most compact, strongest tool in its class. We've added even more value to the Hot Knife with the development of both the GJA3G and GJA4G hot knife groove blade base sleds. This broadens the range to incorporate the use of Groove Jet blade material NWFW.

Tech Specs

* This is limited-time-use hot knife tool.

To avoid overheating and damaging the hot knife, depress the trigger for 15 seconds, then release the trigger for 15 seconds. Continue this cycle for a maximum of 5 minutes. Then let the hot knife rest for 2-1/2 minutes. Using the knife longer than 5 minutes at a time will cause heat damage and is not covered by the warranty.
