The Engel Hot Knife is fantastic for cutting and sealing synthetic ropes and textiles in one hot cut. Particularly when making kites, bags, tents, or anything with textiles this is faster by a factor of 10 than scissors, more accurate, and also seals the edges against fraying. It has two blade types, one long and arced, great for fast large things, one pointed and small for detail work. The fact it has a work light directed at the blade is a tremendous detail only the German’s would have thought of including. I use it for other things as well, like sealing plastic bags and various plastic welding jobs. This is probably a misuse of the tool, but periodically I find that useful. I own two of these, and have owned them for 5+ years, and I love them.
