Quote-"Line Welder System

Yield a virtually indestructible fishing knot without actually tying one. This fishing line welder attaches the line to the hook, securely, in 30 seconds.

Picture shows a "thing" about the size of a flashlight with a flip-up lid. Looks like a piece of heat shrink tubing around doubled line after it is put through a hook eye.

I can loose a lot of flies if improperly tied for $200. Someone has to be kidding on that thing.
