The Perils of Making Jewels

Behold, my fingertips are sacrificed to my art. It is right to sacrifice your fingertips, therefore let us chop them all to heck.

These, people (who might, or might not, be reading), are giant slices inflicted on my defenseless fingers in the cause of making beautiful things for strangers to wear. Think of the deepest, most painful paper cut you have ever had....and magnify it by 2x. Just 2x, it's painful, but it's not life threatening.

What awful piece of dangerous equipment maimed me in the awful way?

Cue the Jaws theme music...dnn dn..dnn dn....dn dn dn dn dn....

But what was I making, when that horrible injury happened?
