Greetings my friends: I gratefully learned to shave on the sound principles generally espoused here at TSD. Before I undertook a 30 day rule, I confess that I played with my gadgetry to find stuff I wanted to use for a month straight. When it came to blades, I really wanted to use Astra because of their generally good reputation. Unfortunately I just couldn't find a comfort level for me. I chalked it up to my inexperience and moved into 30Day with Feather. When I started testing blades, I found that I liked everything BUT Astras. Wierd huh. I could successfully use Derbys, Feathers, and everything else I had, but I just didn't like Astras. Not bad, but inconsistent feel, use, and result. I chose to get one of those Focus Dynamic 1/2 DE Single Edge Razors because of the reports of the really close, comfortable result it can deliver. 1st up Feather - great, 2nd up Derby - good results, 3rd up Sharks - good results, 4th up GSB - great, 5th up Astras, kinda rough (like a dirt road.... gets you there, but you know you've been on it). The beauty of this tool is that if loaded and used correctly, it is idiot proof. It always shaves at the proper angle. THEN, when I loaded up the second half of the snapped Astra, I could hardly believe it was the same blade. It was great! Well just goes to show how futile evaluating DE blades are if you don't track which edge you are using. Leaves a 50-50 chance. My only regret is that it was the last blade in the tuck, so I couldn't repeat to confirm my conclusion. One bad edge! Well wishes.
