I think I may have found what I’m looking for in this youtube video.
It appears someone made their own electric wax knife/pen that seems
to work really well.
If you skip to 2:20 in the time stamp of this video you can see what
looks like a very simple but effective electric wax knife.
Has anyone made their own like this? I would suspect you would want
now more than 40 watts of juice. Would be neat to make your own. I
have heard that one can use an electric light switch dimmer to
regulate the watts for heat control.
