Atta boy Koz...tell a guy who's nicking himself to go ahead and use pressure with the HB!
The best way to use the headblade is to apply "some" pressure on the back, while maintaining the blade on your scalp with and against the grain.
Chris,I use Headblades product called head shed. I used to nick my head a lot until I started using it. This is how I prepare for my head shave. I get in the shower with the hottest water I can stand. Wet my head real good. Then I use head shed, and rub it in real good for a minute. Rinse it out, then immediatly get out of the shower and lather in the headblade mentholated shave lotion. Then just shave as normal.
