I'm only 36, but have had to shave for 25 or so years. I use a straight supplemented by a DE and an electric. Depending on the condition of my face and stubble length. I haven't cut myself with a straight in years other than the slightest little weep spot.
Sunday at the very bottom of my shave line 'bout 3/4" below the adam's apple and slightly left, I knicked myself a decent one. Had to actually open the styptic pen package. Wet it and rubbed it on and whoa what a sting. Felt worse than pure alcohol. Package said sting free. Did I get a bad pen or is that just some liberal advertising.
