Line tool design sample, on copper

I had a request for a line tool, to use for outlining designs. A variety of the line tools could work, but I recommended one about 4mm by less than 1mm, all rounded edges, yet a somewhat sharp tip. I did a little sample to make sure it would move in the way I was describing to the client.

The rounded edges make it more versatile. If you tilt it, just use the corner edge, you can move around curves. You can use it to make a single line, or you can keep pushing the line out to make a wider line. It also leaves a nice texture in the recessed areas. When doing a line, don't lift the tool on and off the metal. Leave it on the metal and let it move as the hammer taps, with your hand guiding its motion.
