Great hot knife works great just as described

i MYOG outdoor gear and can't say enough good about this cutter, at least compared to everything else I've tried. Hot cutting is critical, especially for home production, to keep the synthetics from fraying. It can also just be a heck of a lot easier for certain cuts. I've used this cutter on about 40 yards of cuts so far, and it's been instantly better than the previous solutions I tried that were based on soldering irons. It heats up in seconds, and the analog temperature adjustments seems consistent, and precise enough to get relatively smoke-free cuts. I've used the bottom knife guide exclusively. This has allowed me to not have to cut on cardboard. If I just tip the unit up slightly, I can even cut directly on a plastic workbench. The only improvement I would make is some sort of "outfeed" separator, which would keep the two cut pieces apart behind the cut, like a table saw riving knife. Thin materials requires some finger contortions to keep them from bunching behind the knife near edges, and thicker materials can stay hot enough after the knife to bond back together slightly. Not even remotely a deal killer, as this is SO much better than everything else I've used, but noted for completeness.

It cut fabric and sealed it from fraying. I usually turn the cut edge under and sew it there. Not any more when I cut with this hot knife.

This one really works. I got it because I bought a cheaper one that does not cut fabric well. This one slices through the thickest sunbrella type fabric like butter sealing the edges so they won’t fray.

Temperature control is a bit unruly, but the knife works well.
