i've used them and found them to be excellent. not talked about enough around here. but as always...YMMV. i say order them and try em out. the good thing about B&B is you can always do a PIF or sell/trade on the BST.
The only blade I've ever thrown away after a mere few strokes. I pulled it down my cheek and ended up getting several small weepers in very small area. I virtually never get weepers, and when I do it's only one, and never on my cheeks. When I look closely after using the Bluebird it almost looked like I had shaved with a microscopically serated blade. I didn't haul out a magnifying glass to take a closer look at the blade. Just pitched it and have never gone back to that pack of Bluebirds.
