Don't ya hate foam?
The headaches, the hassles, the loud turkey cutter, pair of scissors after pair of scissors. Your friends and loved ones complaining about the mess.
Can't there be a better, more dangerous, and reckless way?
Well, here is my solution to the problem.
Nicrome wire, a plank of wood, an old power supply, and random hardware.
DON'T BREATH THIS! The foam used for fursuits is really, really toxic when burned. I use a stupid amount of ventilation, and a really nice respirator.
Also the wrong voltage can send a red hot wire flying. Or cause an electrical fire.
I think it's safe to assume you don't touch the wire.
Basically, don't try this at home. If you don't know exactly how I did this, chances are you will get hurt.
Just be safe, and remember, I didn't show you how to do anything

I played around with a few old power supplies before I found one that worked well. I started with a car battery charger at 12 volts, and 50 amps. lol.. don't worry, I was not being practical, and under no circumstances would I say it was a good idea. I just wanted to blow some things up.
I don't have a benchtop power supply, and I was not sure how much resistance this random unmarked gauge of nichrome produced. That, and I had not played with nichrome wire before, so I was not sure of the needed wattage. So I played around a bit. If I had a multi meter that worked it would have made my life much simpler.

Thankfully you don't really need controlled current for nichrome. Being purely resistive, as long as you provide it a regulated voltage, it'll provide the same power every time. I don't know how much your camera or post-processing is making that wire glow, but if it's that bright, don't expect it to last long. To cut foam, it will probably work fine if it's just on the verge of starting to glow.
I've been meaning to make one of these myself; i just haven't gotten around to it yet, nor have i been able to think of a good way to make a frame that leaves plenty of room between the wire and the frame, so I can make nice deep cuts.

Oh yeah, this picture was purely for fun.
I am tinkering currently, and learning as I break things. I researched Nichrome wire much more extensively today, and came up with a much better idea of what gauge I am ordering for my cutting table. And a better understanding of the material than I had even yesterday.
The end verdict. 18 gauge wire, with 2.3v. That should at 10 inches have 0.35 ohms of resistance, drawing 6.5 amps, and 14.95 watts of energy.
I Kinda hope to wake up a little early and find it in town because my table is all set to go. And I wanted an excuse to create a power supply, as I just learned how to make a bridge rectifier, and wanted to make a fully fabricated circuit.

Hahaha, doubters. If I listened to every thing people told me not to do I would have had a much more boring life.
AND FOR THE RECORD, IT WORKS GREAT.
All joking aside.
I wanted to make it myself so I had creative control, the correct ergonomics, and the ability to modify it easily as I saw fit. I hate buying things I can make myself. Hell, this is the exact same reason I started making fursuits myself. It think it's a personality thing. I like to know how things work, and I am a chronic DIY guy. So, the real question is, what kind of person would just buy one?

WOW-WEE I wanna try that!!!!!!
Hey, I get it, you work for electric knife company, don't you... Well you can leave your sales pitch at the door mister. I knows what I like, and that harbor freight curling iron gone mad ain't it. I am not some jerk that has never played with foam before. Best move on to the anime kids, they will buy just about anything.
I tell ya, everyones a critic.

I am thinking it is a lower gauge like in the 30's
here are some better noted variables for us.
I measured the wire to be around 5 inches.
At 36gauge, the Ohms are 11.25 at that length = 17v/11.25 = 1.51111111111111amps :P making that 25.73ish watts drawn
that takes it right to the threshold of melting point. So, I think that is the most likely gauge to yield that reaction.
