I have the iKon that Jimmy is talking about. I use the open comb side first and then clean up with the bar side. I find that if I hold the razor straight up and down and then cant the handle back just a little and let the razor do the cutting, that it is a great little shaver. Don't know if you are keeping your chin up the same as with the straight to keep the neck area stretched, but that and just guiding the razor letting it do the cutting may work out for you.

Good luck.
