I don't know about you, but since I started making jewelry four years ago (wow - I just realized it's now been four years!) I have accumulated quite a few tools. I feel a bit like Tim Allen's character from Home Improvement when I see a cool new pair of pliers, or a hammer, or a vise -- Arrrgh, Arrrgh, Arrrgh! :)
You have to take good care of your tools. Your good hammer used on a household nail would ruin the smooth finish. Your good wire cutters used on a metal harder than they are rated for could mar the cutting edge.
As heartbreaking as a ruined tool could be, it wouldn't be the end of the world. Those tools - precious though they are - are replaceable. There are other tools though that are not replaceable. You only get one set ever. And without them, creating jewelry is basically impossible.
And speaking of wire, I tend to get little wire cuts on the joints of my fingers where I pull the wire snug as I wrap. So I cut off the fingers of an old suede gardening glove and cut the tips of the glove fingers off. That way they protect my fingers without limiting my dexterity.
Anyway - I'm sure I will be fine in a few days. But next time I have a lot of sheet metal to cut, I will use my saw for the large easy areas. I will also use a pair of gloves when I use my shears. And I probably will try to alternate activities a bit more to avoid the fatigue or risk of repetitive injury. Because after all, I intend to use these two hands for many, many more years of jewelry design. I'd better take good care of them.
What are some things you do to take care of your most precious tools?
