These gloves are thick, very silky and seem to work well. I tried putting as much pressure on my hand as i could with a knife and cut across it to test it and it held up. So it will work nicely as a cutting glove or working with sharp edge objects.
I haven't tried puncture testing because i don't think that's what they're for.
I wouldn't be able to pick up a 2 pencil or a pen while wearing these gloves but tools are no problem.
