As a daily shaver with a fairly light beard, I thought I would try a smooth blade that wasn't necessarily the very sharpest. In an earlier thread, someone recommended Derby in this regard. So I bought a box of Derby Premiums, and shave no. 1 was quite a surprise. Thank goodness I was in ultra-light pressure mode. It seemed similar in blade geometry and feel (i.e., very little) to Feather, and unlike PPI blades. And like the Feather, ridiculously sharp. Three passes, and no touch up needed or risked. Whew. I'd be interested to see some of you anti-Derby-ites blind test this against a Feather.
