Worked great!
I needed a hot knife to help make ports in a project enclosure. I bought a much less expensive one before the Huanyu that did not do the job; there was poor contact between the blade the heater so the blade didn't heat up efficiently. The Huanyu has several set screws that lock the knife tools solidly in place - they heat up to correct temperatures and cut the plastic project box easily. This was quite a bit more expensive but it got the job done. Very satisfied.

It works... it's good...but it's pricey.
I can't believe this thing costs so much, but it works and I haven't had any issues with it. Seems to be a quality tool. Hard to find good quality tools without paying an arm and leg. And even when you do there's time's when the quality is questionable. You definitely get what you pay for in this case. This is a good quality tool.

High heat, accurate cut
Husband used these as a fabricator for office panels. He wanted one for personal use & has been searching for a while. This product is exactly what he was looking for. The gun heats up quickly, is easy to use, provide an accurate cut & cools down almost just as quick.

Works Great
Just used this on garden fabric, it works fantastic. Just don't get in a big hurry so that the plastic fuses so it don't unravel....

Cuts Rope and Fabric Clean Every Single Time
This electric hot knife cuts through rope and fabric like nothing and the edges come out perfectly sealed. No fraying, no unraveling, no need to hit the cut end with a lighter afterward. The heat melts and seals as it cuts which gives you a clean professional result every time. The temperature gets hot fast. Within seconds of powering on, you are ready to cut. No waiting around for warmup time. When you have a lot of cutting to do, that speed matters. You can work through material quickly without constantly pausing to let the tool heat back up. I use it for cutting synthetic rope, nylon webbing, and various fabrics. All of them cut cleanly with minimal effort. The hot blade glides through material rather than tearing or crushing it. Smooth cuts that look intentional rather than hacked. Build quality feels solid and the tool is comfortable to hold for extended use. The handle stays cool even when the blade is at full temperature. That matters when you are working on a big project and holding the tool for a while. No hand fatigue or discomfort. The included accessories and different blade tips add versatility. You can swap out tips depending on what you are cutting and how you need to cut it. Fine detail work or longer straight cuts. The right tip for the right job makes a difference in the final result. For anyone working with rope, webbing, fabric, or other materials that fray when cut with scissors or a regular knife, this tool is a game changer. The sealed edges alone justify the purchase. Clean professional cuts without any additional finishing work needed. Once you use it, you will wonder how you ever managed without it.

Excellent heat gun to cut material that frays. Multiple fittings for different hot tip requirements. Heats up quickly

Funcional solo que al trabajarlo en medianas jornadas se llega a calentar todo el aparato ocupando guante para temperatura ya que no es tolerable trabajarlo al tacto. Otra es que la navaja se enfría con cortes largos esto es obvio pero hace que tengas que subir la temperatura para eliminar esta deficiencia por lo cual se calienta todo el aparato. Esperemos ver cuánto tiempo trabaja.

I bought this hot knife to make many cuts in the landscape cloth for my 140 x 30 ft greenhouse that grows hot peppers. it cuts and fuses the edges beautifully with d shaped fabric knife and fabric stabilising foot on the high setting. be sure not to rush the longer cut or it won't fuse in some spots and you could get fraying.. i love this because using scissors leaves loose ends that will continually fray when moved or if there is a breeze through the place, creating horrible trip hazards. looking forward to buying the attachment to use while routering out a hollow in foam pads for under our hydroponic tomatoes.

It does exactly as it says it will… my only wish is that it came with a manual.. other than that it’s awesome. use safely though!
