Hello everyone,
I'm new to the forum and thought I'd weigh in on the discussion. I use to use cheap clippers, Oster adjustable, in which i would losen the screws holding the back blade on and pull the back blade as far back as possible and then tighen the screws. That would cut pretty close. More recently I bought a Remington Titanium Precision clipper and am quite happy with it. It's as close to a blade shave as I ever had.
cheers
