First folding-straight shave!

Controlling and eliminating irritation is all about technique. As you learn what angles provide the most efficient shave, you will also learn how much pressure, if any, to apply. You will also learn the limitations of your skin, and whether it can handle 3 passes plus touchups or if you need to cut back and take it slower...

Well said. Getting the angles down is key. At the end of the day, the fewer strokes of sharp steel across face (or head), the less irritation. Maximize beard reduction while minimizing the number of strokes needed to get to your desired level of closeness, and you've achieved shave Nirvana. (Of course, getting there is half the fun. )
