I want to buy a hot knife but I have no idea how to look for a good quality inexpensive product. Any brand recommendations? and where do I buy one? How do I find out how many watt I need or what kind of blade is suitable? Mostly I will be cutting LW synthetics like cuben, silnylon, primaloft, supplex, velcro etc.

Any advice will be greatly appreciated.

None of the items you mention need to be cut with a hot knife.

i would agree with Ayce. if your looking to get a hot knives to cut fabric they really work better with thicker fabrics.  I’ve got a bench top cutter box used for line, gross grain and zippers that I love Rochford supplies has some good prices on upholstery supplies but google works good too.

For cutting Silnylon, cuben, etc. I would highly recommend a rotary cutter. OLFA makes quality products that last a long time and are still a good price.  You’ll need a cutting board as well which aren’t cheap but last a very long time.

Depending on the types of cuts you make you can buy different size cutters.  If all you do are long straight cuts you might start with the 45mm or 60mm cutter.  If you are making lots of curved cuts then I’d probably start with the 45mm or even go with the 28mm which will make even tighter curved cuts.

I use the Weller soldering GUN with the “knife” attachment. It gets quickly hot, and goes through synthetics like butter. It’s a perfect tool as it both cuts and melts the cut, so there is no fraying. It works great for Momentum Pertex, and sil-nylon. The KIT is available almost anywhere. Very affordable price, and durability, as opposed to actual “hot knives”
