Micromatic Clog Pruf and a Gem coated stainless blade.
Today I put a Tesco own brand blade (Israeli Personna apparently) in my weird English-long-comb-sort-of-new-improved with the odd keyhole shaped holes and very short rounded studs in the cap.
If anyone knows anything about this razor or its date I would love to know - it is a fantastic shave, an effortless BBS today.
