So, I guess it should come as no great surprise that the jewelry I wear is tool centric.
Specifically, bolos and belt-buckles.
An excellent source of miniature tools is the once a year - Craftsman metal tool ornament sales in the stores.
Ironically, all made in the U.S.
First, buy the ones you HAVE to have for the full $9.99 each.
Second, wait for the inevitable 1/2 price sale, and purchase duplicate extras - at half-off.
Finally, buy up the last of the metal ornaments (resins break too easily to wear) at around 60 percent off - limited to whatever is left of the ornaments.
The key is in the hollowing-out of the back of the hammer head.
You gotta leave a rectangular section, projecting in back, to hold the metal belt loop.
And, either "carve out" or add a post to the other end, to fit-into your belt's size adjustment holes.
I have great memories of my dad and his bolo, huge belt buckle and snakeskin boots. He was involved with the rodeo when it came to town. He and my mother were bigtime square dancers. She had fun jewelry as well.
