I recently bought a 1971 Gillette plastic handled Superspeed. I use this razor as a shower razor for a quick shave if I'm in a hurry. I used it with some Headslick this morning and an Israeli Personna blade and the results were fantastic!!! I got a DFS in about a 5 minutes...The Personna blades are a dream in that razor!!! Way better than the Merkur blades I started with...
