Been there, done that. Was grooming a yorkie, took the comb (With clippervac on!) from the back to the front of the head, when I heard a clink. I looked down and thought, "Hey, why is there a comb on the....uh oh..." I looked up, and I'd taken a #40 over the head! Thankfully I was skimming but it was still pretty short. The owner laughed and tried to pay me. I just couldn't take her money, lol.
Anyway, I bought the Wahl stainless steel combs after that, problem solved.
