My Favorite Tool:
Why is this my very favorite tool aside from my own hands? Because it has saved me hundreds of dollars in lost wire. At a mere $25 or so, this flat clamping soft jaw plier can also save you a lot of money. If your wire gets a kink or several kinks, all you have to do is gently pull it thru these pliers to straighten it again. Seriously, this is simply the quickest, easiest and most cost effective way to straighten almost any tangled, tented or kinked wire. I never work without it anymore and only wish I discovered this little baby in my early wire years. Trust me, it'll become essential to you if you haven't used it already.

Sunshine Polishing Cloths

I’ve used these cloths for years now and they can clean wire better than any other cloth I’ve ever tried. They will clean the dirtiest wire and are great for last minute polishing and shine. Be sure to wipe wire surface with a soft cloth or paper towel after use.
