A little background - I've been using straights exclusively since April '07. I've got around a half-dozen razors in rotation. Then there's this 7/8 Henckels Friodur I bought last summer.

This Friodur cuts me up worse than any other razor I own. Little nicks and weepers, in random spots that change from day to day. I've used this razor enough times to get comfortable with it, size is certainly not an issue here (similar sizes in Filly/W&B/Wosty), and it is certainly sharp, so I'm at a loss here.

Most of my others have a nick here or there, and probably over half of my shaves result in zero blood loss. Except the Friodur. Any ideas?
