The "Slim" Gillette Adjustable razor superseded the Fatboy and had an original retail list price of $1.50 (45 cents less than the Fatboy) which was later adjusted to $1.79. The Slim is made of a very durable nickel plated brass.There are nine adjustment positions on the adjustment dial with "9" being the most aggressive and "1" being the least aggressive. It also has a twist-to-open mechanism at the bottom to allow for changing or rinsing of the blade. There is also a quarter turn to firmly lock the doors down on the razor blade. The Slim compared to the Fatboy has a more compact head, a longer narrower handle and is lighter. The easiest way to recognize a Slim is to look at the adjustment dial; it has both horizontal and vertical knurling as opposed to the Fatboy which has only vertical knurling on the dial. The Slim was produced continuously each quarter from 1961 (G-3) until the last Slim was produced in 1968 (N-4). The G-3 and G-4 Slims overlapped with the end of production of the Fatboy whose last date code was G-4. The G-3 Slims appear to be much more rare than the G-4's giving rise to the theory that Slim production started in the later half of the third quarter and G-4 was the first full quarter of Slim production. The Slim was initially packed with six Super Blue carbon steel blades. Gillette was late to the party with the introduction of stainless steel double edge blades. Its competitors Wilkinson, Schick and American Safety Razor beat Gillette to the market with this type of blade and sales suffered at Gillette until they caught up. But soon in 1962 saw the introduction of Gillette's new stainless steel blades so the Slim was also packed with a reduced count of two Gillette Stainless Blades that year. Fully caught up by 1965, the Gillette Super Stainless Blades 2-Pak was introduced into the Slim packaging in 1965 (K-4); the K-3 Slim still contained the 2-pak of regular Stainless Steel blades. The main difference with the Gillette Super Stainless Steel Blade aka "The Spoiler" was the introduction of a "miracle plastic coating baked onto the edge" - purported to cause a noticeable reduction of "pull". Also, in 1965 Gillette changed their logo from a Serif type font to a more modern looking San-Serif font. The new logo can be see to being used on the third quarter K-3 Slim printed packaging. However, Gillette continued to use the older Serif font logo on their case molding for many more years - plastic molds to expensive to change? The Slim weighs in at 71 grams.
1961 G-3 to 1963 I-4 Gold Insert cases.
1964 J-1 to 1966 L-1 Red Insert cases.
1966 L-2 to 1968 N-4 Black Insert Cases.
1966 L-1 was the last of the red insert Slims. Starting in 1966 L-2 Gillette introduced the black insert Slim cases; dropping the word "SLIM" on the packaging.
Notice the cased 1966 L-4 above has a new higher price of $1.79 and one of the cased 1967 M-1 below has a price of $1.50. Then there is another cased M-1 with a price of $1.79. These date codes were all verified too! Leave it to Gillette - many times they were inconsistent! Or, they were staggering the roll out of the higher priced products to test how markets were accepting it.
Here is an early Slim from 1961, 1962 or 1963. Notice the Gold on White Case. Blades would have been either Gillette Super Blue or Gillette Stainless Steel depending on the year.
Here is a 1965 K-3 Slim. Notice the Blue on Light Blue case with Stainless Steel Blades. This was a special baseball edition for only $1.00 retail list price. This was prior to the introduction of the Super Stainless Steel Blades later in the year.

In the USA and Australia they marketed this new Gillette Adjustable razor as the "Slim". However, in the United Kingdom the Slim was marketed as the Gillette Adjustable Mk II. Maybe "Slim" was not considered a sophisticated enough or proper name to be calling this new version of the adjustable razor. So, in the UK the Fatboy was considered the Gillette Adjustable Mk I and the Slim was considered the Gillette Adjustable Mk II.

Minor Changes to the Slim Design
The following Gillette design changes to the Standard Slim were documented by master razor collector Joachim Duwe. He was gracious enough to provide the following photographs of his discoveries.
In 1962, Gillette changed the design of the bottom edge of the positioning bar/door actuator between the H-3 and H-4 manufacturing models. There do exist some H-4 models with the old style positioning bar/door actuator therefore the change was made in the fourth quarter of 1962. (see photo below to the right.)
In 1964, Gillette changed the design of the hinge tab of the doors between the J-1 and J-2 manufacturing models. This change most likely improved operation of the door mechanism providing less jams when opening the doors via the twist-to-open knob. As pointed out by one of our readers, Michael Gricksch, there do exist some J-1 models with the new tab (see photo below to the left) and thanks to Kevin Brady, there do exist some J-2 models with the old tab (see photo below to the right). This was typical of Gillette to keep using their supply of old parts while also incorporating the new parts
Gillette Slim Oddity: A N-3 Slim but with a Super Adjustable Bottom Plate!
Here is an odd Gillette Slim. It was manufactured in 1968 near the very end of Slim production. They had just started producing the "Black Beauty" Gillette Super Adjustable so bottom plate parts for both types were available at the manufacturing facility and they were out of stock of Slim parts. So, some enterprising Gillette employee substituted in bottom plates from the Super Adjustable parts bin!
