A store I worked at many years ago had a couple of these. One held a
spool of package tying twine, the other, a couple spools of ribbon
for gift wrapping. They sat right next to a larger dispenser that
held the gift wrap paper. So I’ll second Jon Harpers post.
But you could use it to hold spools of just about anything you want
to “dispense”. string, ribbon, coils of wire, tape, Knitting yarn,
etc Heck, you could even just hang some of those pairs of pliers on
And no, it’s not a vise, or engraving clamp, etc. Not sturdy enough
for that, and too large for a couple of the suggested uses people
have opined. The knob is just a clamping screw to adjust the gap
between the end pieces, not something to rotate the spindle with, so
it’s not a jump ring maker. Though Veva’s idea to use it to feed wire
to a jump ringer is a decent one.
