My fav blade was GSB, then I tried Nacet. Both are very fine blades. However, after reading about Polsilver by many mentions by forums, I thought I'd give Polsilver a try. £5 For 30 blades , post free from a seller on Amazon from Switzerland. Wow, have shaved for 4 days, EJ razor and in my opinion, this blade is head and shoulders above all others. A close and very comfortable shave. No irritation etc etc.
