So I'm trying to do my foam waterfall build and I can not find a HOT KNIFE ANYWHERE?!?!?!?!?


Can anyone direct me to where you bought yours?

I have tried ...

<--awesome multi-tool, but the hotknife is 1/2" long and meh...

Amazon.com: Hot Wire Foam Cutter: Toys & Games <--I tried a diff brand, same thing....totally useless (broke within 30 seconds of using)

Amazon.com: The Styro Wonder Hot Knife Cutter Plus: Arts, Crafts & Sewing <--also diff brand, same thing....even worse than the one above



I'm now considering buying : Amazon.com: Electric Hot Knife: Home Improvement as it is the only hotknife with a decent blade I can find under $50-60...

also found this: http://www.wirecare.com/Hot-Knives.asp?gclid=CLjk4NyN4q0CFQdjhwodgjObTQ the $45 hand-held one?

EDIT: I need something that can comfortably cut 1-1.5" foam

You should be able to find one on Ebay.

This one looks like it should do the job.

They are also used in beekeeping to uncap honey for extraction.

Honestly, I've got 3 different hot knives / soldering irons that each make different cuts much better than the others - it all depends on what shapes you are trying to make.

Most of the time I keep coming back to a weller soldering iron kit that came w/ several different knife tips, but that is because I like to make jagged, shattered looking "rocks". However, this setup doesn't make rounded, eroded ones too well?

I've been eyeing these knives for a while

Grapefruit knifes are great for cutting foam!

you can even make your own with a few parts and a car battery if you dont feel like paying money for a small project

@motydesign: actually, thats what I did.....but I just used an AC Transformer to step it down

my wire isn't getting super hot though, its not the proper type of material or something....

try a thinner wire then, itll up the resistance.
