Hate to add any new nonsense when it comes to blades and razors, but this morning I tried a Feather Pro light razor blade- cut down with a pair of sheet metal cutters and the shave was beyond anything I could possibly imagine. Smooth, easy, and no blood letting. Why, I have no idea. I read about that English guy who figured this attack at whiskers out and decided maybe he had something. And, I can conclude now he really does!! The shave with a Chick injector blade is damn good, but the cut down Feather blade is more than that for sure!!! I used a Schick Hydro-Magic razor. And, my 68 yr old arthritic hands managed to handle the blade cutting and installation without any blood. Didn't take more than 30 seconds?Care must be taken but it isn't brain surgery either. No more danger than the old opening can with the provided key idea! Can you sharpen your kitchen knives? The shaving was so quick I was amazed. No burn, no nothing!! The result was the very, very best. I have shaved with the very best D/E razors and many other S/E razors, and this was equal to the very best that I have ever used!!! Easier and quicker too!! And, other than missing the sword like handling of my D/E razors and blades, the heft, the weight, the idea?, I have to admit the S/E cut down Feather razor blade shave, was truly superior. The best IMHO!!! That's my story and I am unanimous in my opinion of it!!! WOW, is what I say!!! Truly WOW and what FUN!!!
