How to Date a Randall Made knife by the Blade Stamp?

Dating a Randall knife can be a real chore! The more you understand about the frugal nature of W.D. 'Bo' Randall and the 'First in, Last out' policy of the shop, you begin to realize that it's more of a range rather than an exact date. The more information you have on the subtle changes to production through the years, the better you can narrow that range and avoid buying a misrepresented knife. Blade steel and stamps have had slight variations over the years; here are some things to look for.

Steel

The earliest RMK blades were made from steel automotive springs. Since the early 1940s, RMK's primary steel has been a 'High Carbon' Swedish 01 tool steel. In addition to the Swedish 'tool steel,' RMK also uses 440B Stainless Steel. The debut of the 'Fish,' 'Oyster,' and 'Barkeep' knives in the 1940s marked when stainless became viable for future knife production, though some stainless was used as far back as 1938. ATS-34 was introduced in the early 1990s as an option for models #9, #10, #24, and possibly a few 'non-catalogue' models.

Blade Stamps

In the early 1980s, the United States Postal Service (USPS) switched over to two-letter abbreviations for each of the 50 states. Some blade stamps have FLA., and others have FL. To some degree, this creates a line between pre-1980s knives, but this is not totally accurate.

The stamp maker made up a few stamps at the time with the 'FL' logo in both large and small variants; these were used only on stainless steel knives. Old and new versions of the stamps are in use. You'll find that the 'FL' stamp is interchangeable with the 'FLA' stamp, but only on stainless steel blades and only on those made after 1984. You won't ever see a 'FL' stamp on any legitimate O1 'high carbon' blade of any size as made by RMK.

FL & FLA stamps

Around 1958/59, a double-stamped 'SS' marking was first used on Orlando-made stainless blades, not the 01 Swedish tool steel. This practice continued until around 1963 when one of the S's was dropped.

The single S was usually stamped low on the ricasso, known to collectors as the 'Low S.' This method continued through at least 1965.

1963-1965 the 'Low S' Stainless stamp

The S was then moved up and adjacent to the RMK logo stamp. These adjacent S stamps are known to collectors as the 'Separate S.' They were made in Orlando from 1966 to 1971.

1966-1971 'Separate S' Stainless stamp

By 1972, stainless steel blades from Orlando are stamped with an RMK logo stamp with the S integrated.

From 1957-1977, RMK contracted to have their stainless blades forged in Solingen, Germany. This gave them an expedient, low-cost alternative to meet demand as the United States entered conflicts in the Southeast Asian war 'Vietnam.' The first Solingen blades were used on the Model #14 and #15. They were marked vertically on the ricasso as 'RANDALL MADE, SOLINGEN GERMANY.' By 1963, the marking changed to a single vertical ricasso stamp of 'STAINLESS' with the Solingen logo etched horizontally where the Orlando stamp normally resided, often with a single 'S' etched in too.

RMK LOGO Stamp Letter Spacing Pre-1973

From the earliest, the Randall stamp on the blade remained seemingly unchanged. The 'O' in Orlando began about a half space indented from the 'R' of Randall. The comma between ORLANDO and FLA was about half a letter high, and no space separated it from 'FLA.'.

About the mid to late 1960s, the stamp was apparently changed slightly. The comma between Orlando and FLA was reduced in height, a small space was introduced between the comma and FLA, and because of that, the 'O' of Orlando was moved more directly under the 'R' of Randall, indented only about 1/8 letter or so.

Example of the letter spacing changes on the stamp from 1950s to late 1960s

Understanding these nuances can help you better date a Randall knife and appreciate the craftsmanship and history behind each blade. By paying close attention to the steel type, blade stamps, and subtle changes over the years, you can make a more informed purchase and avoid misrepresentation. Happy collecting!
