Jhua Hot Knife Foam Cutter Electric Styrofoam Cutting Tool 36W Hot Wire Foam Cutter Electric Foam Cutting Machine Pen Hot Pen 15CM Styrofoam Cutter Cutting Tool Kit

I cut a lot of 1" thick insulation type foam for Mardi Gras projects. this thing rocks!! cuts like butter and is super fast! i'll probably burn it up since I cut so much but I"ve burnt up plenty of them before. Will buy it again when I do!! Super easy to use and the length of the cutting wire is awesome!

I got it to "cut" through Styrofoam to insulate a tote for a cat house. It worked like a charm for about an hour, on and off. I was slow and precise. Before I was done it just stopped working. Tried everything, but it was just finished. I would be ashamed to be the designer of such a flimsy and dishonorable tool. It was made in China, that is why I used the word dishonorable.

Using it to cut styrofoam for house insulation, and cut the time for custom fitting the blocks, in half. On-Off switch makes it easy to shut off for extended periods. Heats up quickly. Do need to practice how fast to go through the pieces, in order to keep the wire hot. Excellent addition to the toolbox!

No funciono para mi no calentaba lo suficiente para hacer los cortes que necesitaba en el poliestireno y termine usando el cutter como siempre

The knife is an invaluable tool for my foam cutting project (scenery and supports for a model railroad). The cord however is short, which I supplemented with a plug-in extension. It heats fast and can cut thick foam.

It makes cutting styrofoam insulation less messy and the cuts are more accurate than using a mat knife or other blade. I used it for 1" and 2" thick insulation and it requires more patience with the thicker sheets. I found that by holding the blade at an angle (45 to 60 degrees) and adding a spacer under the styrofoam(so the hot tip was sure to penetrate) that it resulted in a nice sealed edge. You have to let the knife do the workinstead of forcing it through.

Bought 1 of these for the longer hot element. After cutting about 2" te running light on the power pack went out, it got cold and it never worked again. SO...I returned/replaced it with the same thing. The new one worked for about 3 minutes before it died. I tested the volts & amps on our power outlet and it's fine.THESE ARE COMPLETE CRAP - a total waste of 10 days waiiting and returning, plus running them back to the return location. *** DO NOT BUY IT! ***

It works great for cutting flower frogs. Quick and easy and there is little or no mess to clean up.
