I was putting my newish 150 piece Chinese Craftsman set to use the other day when my Jeep wouldn't start. I went to grab the 10mm wrench and had a needle like burr become imbedded right into my left index finger. Of course this was in a public parking lot on a humid 85 degree day which just added to the drama. Not wanting to start a Craftsman hating thread, but just wanting to warn others about the potential issues. Might not be a bad idea to take some fine sandpaper to the tools either. Bought the set for $45 around Thanksgiving. Lifetime warranty. Still not a bad deal. Turned out to be my neutral safety switch by the way.
