I used it to carve rifle cartridges with the Pelican 1750 foam case (http://www.amazon.com/gp/product/B000AOMA1S/ ref=wms_ohs_product?ie=UTF8&psc=1). I love being able to control the temperature and as you'll find if you keep the heat high, the wire cuts too quickly and you get jagged cuts. Reduce the temperature to 4-5Β°C and it will cut slowly enough to get nice, smooth, straight cuts. Also, the price of this product was a bit higher than expected, rather poor quality. I'm deducting a star for this product. for two reasons: 1) the included instructions are practically useless, I threw mine away after trying to use them for a while. 2) Over-tightening the bottom wire clamp will break the wire in the clamp assembly each time. . Once you get used to how tight you tighten it, you can easily get perfect results almost every time (without slipping or breaking the wire). However, I hope they make it so you don't have to figure out why you keep breaking the wire.
