> Works for the sides, but how to do make a smooth transition to the top? Without cutting it equally short everywhere? My technique is to keep the machine at the same angle (blades roughly vertical) while moving upwards: as it slides over the curvature at the top, the distance between the base of the hair and the cutter increases smoothly. This is with the biggest comb clipped on. I then remove the comb and use my fingers instead, sliding the blade on top of them, to get a longer cut than with the combs. The machine I use is a Panasonic ER-1611 which is not cheap, but here you can see a picture including a side view for the angle: http://tondeusebarbe.fr/wp-content/uploads/2015/05/test-panasonic-er-1611.jpg http://tondeusebarbe.fr/wp-content/uploads/2015/05/test-pana... I've also used before a cheaper Phillips that worked fine but wore out after some years, and the first one was a Solac that I still have in Spain and works as new. The technique works similarly for all of them, but both the Solac and the Panasonic were sold as "for professional use" and they do work noticeably better. I've been doing this since shortly before starting my military service in Spain long ago. You get better with practice. Oh, and try to arrange a couple of parallel mirrors so that you can see the back of your head.
