I've been cutting dh's hair for the past several years. We've had the same clippers for about 7 years and after reading through this thread, maybe its time to get a new pair. I cut his sides to 3/4" with the guide on the clippers and then cut the top with sissors to the length of my three fingers. It is easy, but I will never live down the time I started on the back of his head with the clippers but forgot to put the 3/4" guide on! All I said was oops! and he took off to find a mirror.
