Then why would you want fingerless gloves?
Touching people in an EMS environment= Nitrile gloves
Using tools = Regular mechanics gloves.
You can buy a decent pair at harbor freight, Home Depot or any auto parts store.
As an aside, for a while I used a pair of Petzl Cordex climbing gloves as my "ems work gloves" but the fabric back caused me to get sliced by a sharp piece of metal when doing an extrication class with some students and they stink pretty bad when they get wet. But super comfortable. I still use them as my work gloves at home.
