Because it's cold out there. Just like saw blades and screwdrivers, they're tools, and we need more than one kind. For myself, I usually wear gloves with the fingertips cut off - but then I don't live in the Adirondacks like Ken, the owner of these gloves. (Ken, by the way, just had a pacemaker installed in his chest and is feeling much better - probably out splitting firewood at this moment, at age 94).
When my fingers get cold, I lose all sensation (except constant pain). I dream of a glove that keeps fingers toasty warm, allows me to feel what I'm touching, allows a good grip on a chainsaw or a wire nut, and allows me to pick up a 6d finish nail. And while I'm dreaming, how about one that allows me to touch a live 240 volt wire - or hold a demolition hammer without sending vibrations up my arm? I keep thinking there must be a better design for gloves, and maybe there is. What do you use?
