Schick is the second-largest razor family in this archive and it works in the opposite way to Gillette. There is no number to read and no letter to decode. The entire dating method is a classification of shapes, published by the collector Alan Appleby and reproduced in the reference sites ever since, and it comes with an honest warning that is easy to skip over and important not to.

What the classification says about itself

The guide describes a succession of subtle changes and refinements occurring on a regular basis, and concludes that those clues, plus packaging, allow the razor to be dated with some degree of accuracy. That is the claim: a degree of accuracy, with packaging standing alongside the razor rather than behind it. The same guide carries a footnote on the author's page stating that the types were assigned by the author for classification purposes and are not company design or model designations. Any answer about a Type J or a Type L is therefore an answer in a collector's system, not in Schick's own catalogue.

The types, and the eras they cover

The types run from A to O, and the sequence is the era. The shape of it:

The overprint: a brand era, not a year

Schick razors carry an inscription on the head, the rivet or the handle, and it moves through three states. Before 1946 the razor reads Schick, from the Magazine Repeating Razor Company. From 1946 to 1955 it reads Eversharp Schick Injector Razor, under Eversharp Inc. After that it reads Schick Injector Razor again, with Eversharp reduced to a small banner on the two initials. The ladies' line from 1962 reads Lady Eversharp Beauty Razor.

This is genuinely useful, and it is worth being precise about what it gives: a brand era, not a year. The overprint tells you which company was selling the razor, which bounds the period, and it does not tell you when the razor was made inside that period.

The packaging, treated as an equal key

The classification elevates packaging to a second key of equal standing, and the sequence it records is long and specific. The early razors come in a long rectangular white cardboard box, then a leather or leather-over-metal clamshell, then a maroon bakelite clamshell with a printed lid, then a black bakelite clamshell with a gold-and-red box, then a tan leather case with a lifetime guarantee on the bottom from 1939 to 1945, then a black art-deco stand-box with a container for used blades, then a wartime navy or red clamshell in cardboard, then the brown and cream box of 1946 to 1953, and finally the first plastic case in red and clear in 1950 to 1953.

The honest caveat attached to that list is that one case can serve several types. The same black bakelite clamshell appears on both the Type D and the Type E, so a case narrows a window rather than pinning a year.

What you actually get, and what to watch

A Schick injector can be placed in a type, in a brand era and in a packaging era, and those three together give a window of years that is often narrow and never exact. Two wrinkles are worth carrying.
