As new wetshavers come into the forum and begin to learn about the different razors available, the "which Gillette is this" question comes up pretty frequently so I thought I'd provide a snapshot (pun intended) of what's available on the used market (read E-bay). These are the razors I personally own and there are a couple of razors absent such as the Aristocrat and Toggle but hey, it's all I got!! It's not likely I'm going to spend the $100.00 plus that the toggles are bringing now. They were only made one year and that makes them pretty popular with collectors. I hope some find this helpful. Shave quality is my opinion, and as always, YMMV. Top row left to right: 1. Fixed head, all metal screw on handle. Poor to average shaver in my opinion and I don't personally recommend it. 2.Gillette travel razor. These came in several different holders from faux leather to plastic usually including a box of blades. Handle is really too short to be of much use. This particular razor was made in 1967. 3.Superspeed. This is one of my favorite razors. The head design is a little different than the later superspeeds and gives a very nice shave. It remains part of my rotation. This razor was made in 1953 and is a twist to open design, sometimes called "silo" opening. 4.Superspeed. This is a later version with a black handle. Not as good a shaver in my opinion but these are very inexpensive so might be worth a shot if you're just starting out in wetshaving. This razor is also TTO. 5.Superspeed. Gillette made 4 types of this version with slightly different heads and different colored tips on the handles. The one shown has no color, then there were superspeeds with blue, black, and red tips to the handles. The red was the heaviest of all the superspeeds. Bottom row, left to right 6.Enter the adjustable. This is one of Gillettes first adjustable razors. It has a moveable ring just below the head with numbers 1 to 9. One being the least aggressive and 9 being the most (the blade will be closest to the safety bar on 1 and gets progressively farther away as you dial up the numbers.) This is my favorite adjustable Gillette and is a very popular and a good shaver. It has a nice weight and balance and is a very solid, durable razor. It is sometimes referred to as "fat boy" or "heavy duty". This particular razor was made in 1959. 7.Ladies non-adjustable razor. This was marketed to the ladies for their particular needs. It is light blue with little stars on the handle below the head. Not a bad razor for the guys either it you're secure in your manhood! I like the long handle but it does belong to my wife now. It was made in 1965. 8.Slim adjustable. This is a similar razor to the heavy duty but with a slimmer handle and the head is slightly thinner. I can't seem to get as good a shave with this as the HD which I attribute to the difference in the head design. A lot of guys use them however so they're certainly worth a try. This is a 1966 model. 9.Black handle adjustable. Same as above but with longer, black handle. Again, I know guys who love this razor and it also would be worth trying. This particular razor is a 1973 model. I've never owned or tried any of the open comb models nor any of the plastic handled Gillettes made in England. I wouldn't recommend them based on what I've seen. Gillette razors have increased in price recently due in part, I'm sure, to the shaving forums popularity and resurgence of wetshaving. The superspeeds sell from $3.00 to around $10.00 and the adjustables sometimes fetching $30.00 in mint condition. Give them a try....they might be just what you're looking for. Mike, here you go: The razor on the left is a Tech and is a 3 piece razor. Next is the 1953 superspeed and the black handled superspeed. As you can tell, the head is a little taller on the older razor than the newer black handled superspeed next to it. This could possibly create a slightly different blade angle relative to the safety bar and is what I attribute the difference in shaves to. Next are the two adjustables. The head comparisons are just like the two superspeeds above with the heavy duty on the left having the slightly taller head than the newer slim model on the right. Again, I notice a difference in shave quality between the two, but both are popular Gillettes so, it could just be me or my technique with the two razors. I believe most in this forum, myself included, consider the newer Merkurs to be more aggressive razors especially the Futur and Vision. The Gillettes can be an inexpensive and excellent starter razors and you may even find they are your razor of choice. Coupled with a Feather blade, I can get great shaves with my 1959 fat boy adjustable or my 1953 Superspeed. There's something about shaving with a 50 year old razor that I just enjoy.
