I know that blade experience is wildly personal and varies enormously by razor, but I am conducting trials with my Henson AL13 + (the mild one) to see which blades are best for me. I would love to hear experiences from other Henson users or reactions to my experiences. Here are my observations so far: RK blades sold by Henson -- not as sharp on the first pass. Second pass is comfortable. Post shave feels great -- no irritation. Feather -- close shave, but afterwards my face felt irritated, needed to be soothed with lotion. I have this same reaction from Feather blades in my Feather AS-D2. Personna Platinum (German) -- close shave, rivaling Feather. Smoother than Feather, but still felt some irritation later. Gillette 7 O'Clock Super Stainless (green) -- not as sharp as I would like, but not especially smooth, either. Astra SP -- better than the Gillette green blades, but not as close or smooth as I wish. Nacet -- sharper than Astra, but not especially smooth or comfortable. Wizamet Super Iridium -- comfortable shave, not as close as Feather, but good enough. Face felt great afterwards. Tatra Platinum -- comfortable shave, fairly close. Face feels good. Gillette Wilkinson Sword -- comfortable shave, fairly close, no irritation. Gillette Silver Blue -- close, smooth, comfortable, no irritation. Face feels good. Phoenix Artisan Accoutrements Platinum Strangelet -- initial first pass felt a bit rough, but quickly smoothed out. Smooth and comfortable. I still have a drawer full of blades to try!
