This razor for head shaving is truly a design tour-de-force. It looks and feels really slick and, most amazingly, it works like a charm. From the HeadBlade site:
"Unlike a conventional razor, the HeadBlade makes your hand (and fingers) the handle. This gives you more control. When your fingers can touch your scalp you have a much better understanding or 'feel' of what you're doing. The patented suspension of the HeadBlade gives you even more control; you don't have to worry about the angle of the blade. Think of a conventional handled razor. It's like a unicycle and only touches your head at one point (where the blade is). This is very difficult to control (both the angle and pressure of the blade). Especially if your fingers aren't in contact with your scalp. The HeadBlade, in contrast, has a suspension and touches your head in two places; like a bicycle."
My head hasn't been this smooth since I last visited Ye Olde Barber Shoppe for the straight razor special. Link (via Cool Tools)
