Hot Knife Foam Cutter Hot Wire Styrofoam Engraving Tip 3 in 1 Tools Kit By Calcor

The wire attachment cuts extruded polystyrene with eases. A little slow, but a very nice finish. The engraving attachment does alright. The knife sucks. I don't know if I'm using it wrong or what, but it does not cut XPS like the wire does. I really only needed the hot wire cutter, so the I think the price is worth it for just that tool.

If you work with foam this is an awesome tool. Easy to use. Highly recommend it. Just get it.My son and I purchased this specifically for a diorama build for his YouTube channel (Will Build Everything). We were making a contoured lake bed out of an insulation foam board and found this tool. It worked great. If you’re interested in seeing the tool in motion you can go to his channel: Will Build Everything and watch his Hollow Knight video on his channel. At the 4 minute mark of the video he shows how the tool works. Since it’s cutting with heat but sure to wear a mask.

Very useful tool for cutting foam and works fine (slow cuts only). Only gripe is the rest is very lightweight and easy to knock over, so be careful or mount it to a sturdier base / create your own rest. In a perfect world the cord would be a bit longer, too, but not a dealbreaker; just makes using with an extension cord awkward due to the weight of the connecting plugs.

I think the tool is useful. I think I was trying to use it on foam board which is not the same as a block of form. Also, my user problem: I never got a consistent cut. I could not keep it at a steady enough pressure and speed to get a clean cut. So, all that said, I still think it would be a great tool for someone who understand the technique and the patience to learn the technique of using the tool.

This is a ok product for beginners, you can change the tips very easy but it not a very good design, I find my tips keep losing up or even falling out in use and there is no heat adjustment, just on and off switch. but heats up and cools do fast, cuts well, if I will get a nother hot knife I would look around for a little better one next time, like I said this more for a beginner or someone that is not using it a lot.

I’m not sure if I received a defective one but it doesn't work! In addition, the long wand attachment broke the fist time I used it.

attachment wires are simple to pop in and out of the handle and have a simple variety to allow for different cutting shapes.I used this to cut 1" pink insulation foam to form rocks & hills for model train terrain. No issues, nice results with clean surfaces, and substantially easier & cleaner than using a knife (no dust and little foam bits).wire attachment is the cleanest cut and burns the least amount of foam. thicker wire "blade", due to the thickness and amount of heat to dissipate produces more foam out-gassing, so best to in a ventilated area (open window). Any wire cutter will have this consideration
