The Hercules SC-590 Electric Hot Knife has a built-in fan which provides continuous cooling, allowing the unit to be used non-stop for your entire project, instead of forcing you to stop every 15-30 seconds to allow your cutter to cool.
The SC-590 kit includes everything you need: SC-590 cutter, one 4" and one 6" flat blade, cleaning brush, hex wrench, durable molded plastic carrying case and instruction booklet.
