I've never used the skip tooth blades. I just use the same blade as I use on the back (#5) and when blending in the skirt I just go straight down the side tipping the clippers outward as I get to the edge of the skirt to give it that "fade" look.
My scare factor is when is comes to using them for the legs and the pits. But now that I am getting my own clippers I need to get up the nerve to do it on my own. I normally have my sister do the pits and I do a pretty choppy job on the legs than fix them up with scissors. I know the key is to lay them flat and not tip them forward but it just scares the crap out of me. Im so afraid that I will cut one of them.
Any advise on getting in done and safely would be appreciated !!
