Kevlar sleeves.
They're cool, but what will you be cutting while you use them?
Wood, mostly, with various power and hand tools. They'll also give me some protection when gardening, since my arms tend to get pretty scratched up by thorny plants, and they'll help when I'm lifting heavy, awkward, rough things like rocks and slabs. I have a pair of kevlar gloves that I got a while ago, and they've been very durable. The only damage to them so far is where they got snarled in a drill bit, and I was able to stitch them up with a little dental floss. The sleeves proved useful yesterday; I was walking my dog and she insisted on dragging me through patch after thorny, tangled patch of brambles, but I was wearing the sleeves at the time, and emerged without any of the usual scratches to my arms and thorn tips stuck under my skin.
