RoMech 200W Pro Electric Hot Knife Foam Cutter Kit - Styrofoam Cutting Tool with Blades

John B: I bought the 200w air cooled version to cut 2” XPS foam for insulating the basement of my cabin, it cuts very well but the short blade that comes in the box curved left after the first use, so the cuts aren’t square. It’s not a huge issue since the insulation will be hiding behind walls, but makes it kind of hard to get a perfect fit in some places.

Amazon Customer: I really like how this hot knife sheets up nearly instantly. It’s very easy to handle, and has greatly improved the edges of my foam cuts.
A bit pricey, though.

Paulie: Just got this delivered today, and never used one before. I used it to cut 4 tombstones out of SPX foam, and I was amazed how easy and fast this thing cut...I mean, wow. Temp control sucks, with no lines, numbers or even ease of use. I would normally knock 1 or 2 stars off for that, but I was so amazed how well it worked, I can forgive a stupid design mistake.

Sharyl E Davis: I had never used a hot knife before and needed better instructions. There was no diagram, and no specific instructions on use. It was difficult to find videos, and I never found a " how to". Ie for fabric you need to use a tempered glass cutting mat. However, once I figured out what to do it worked great. I may do my own video and post on utube so others don't have to struggle like I did.

David L.: I bought this so that I could get rid of all the styrofoam collected in packaging over the year. I didn't realize how much of a PITA getting rid of styrofoam packaging or shipping coolers was until I tried to cut them down with a razor knife... what a mess! After reading the reviews on the wire heating cutters, I decided those wouldn't last long (I had a LOT of this stuff to get rid of.). So I bought this because I could, and I like gadgets and tools. This DID NOT DISAPPOINT!

First, make sure you use it in a well-ventilated area, as most foam products emit noxious/toxic vapors, so ventilation is a must. Keep positive control of this tool, and be careful where you set it down while using it. It becomes red-hot, and it will do some serious damage to the flesh (but it will also cauterize the wound so you probably won't bleed to death if you do something stupid.)

It really does work well, I found myself playing with it as I was cutting down the big foam blocks, experimenting with it; getting creative, and carving alphabet letters and animal silhouettes out of the styrofoam, so I spent two days cutting all of my styrofoam down into little cubes that I can use for packing...

Brent McGillis: Very simple and intuitive to use, just install the blade and you are good to go. This tool cuts through 2 inch thick rigid foam VERY quickly, most likely because it does get very hot immediately. Make sure you have a place to set it down between cuts because this thing is ready in seconds, since it does get so hot I would recommend that you use leather gloves because the potential to burn your digits is quite obvious once you pull the trigger on this device. I use gloves because I am old and fumbly. The reason I bought this device is because I need it to cut insulation panels to fit precisely on my RV motorhome, I am in southern British Columbia a couple of miles from the 49th parallel. I don't care what anybody says, when you live North of the 49th, you are gonna need some skirting and insulation up here in the Great White North and THIS IS the tool to get the job done. It allows you to quickly make nice clean cuts through rigid insulation panels quickly and, it does not look like a 2 year old did it when you are done. I personally have not had a problem with residue being left on the blade, although the tool comes with 2 blades and cleaning brush and instructions on how to use...

Ce couteau chauffant est merveilleux ce qui facilite le travail et fait de belle coupe propre ce qui empêche le ramassage de milliers de bulles lors d’une coupe de styrofoam.
Je recommande ce produit fortement.
