No, they don't. The edges are even worse. Like paper cuts, but you don't realize that you got them until later when the machine oil gets to them and you have deep red slits from your elbows to your fingertips.
My hands always look destroyed from the sharp edges of everything. Halo recessd fixtures, panelboards, grabbing handfuls of staples, etc., rips up my hands like paper cuts. It really hurts if you get a small amount of PVC glue or cleaner on those cuts.
When I was new in this business I always had cuts on my hands. I thought it just came with the job. But, after suffering with this issue, I decided I would work more carefully and pay attention to what I was doing all the time. Of course from time to time I would get cut. It's kinda like learning to stay clean even if you worked on a sewer pump.
I don’t work in the field anymore but every now and then I have to get out and do something just to get out of the office. Sometimes I sort material in the mornings just because I like it too. When I do either these work great: http://garage.mechanix.com/
My men make fun o me but I am pretty sure some of them use them too. They feel really good and you don’t lose any dexterity.
