The Victorinox Long Nail File (LNF) is one of the most discreet and unusual tools ever integrated into the 91 mm Officer Knife platform.
Often overlooked when folded into the knife, it reflects a period where Victorinox still balanced:
- outdoor utility
- civilian elegance
- personal grooming functions
More discreet than a magnifying glass and less visible than a fish scaler, the Long Nail File remains one of the most distinctive features found on a handful of high-end Victorinox models from the 1950s and 1960s.
The Long Nail File
Also known as the Manicure Blade, the Long Nail File is a thin rear-mounted (scissors layers) tool integrating:
- nail file
- nail cleaner tip
Unlike standard nail files, the abrasive surface is hidden on the underside of the tool.
When folded:
- the visible surface appears smooth
- the tool almost disappears into the knife
This discreet integration explains why many users do not immediately notice its presence.
Structurally, the LNF is unusual.
Unlike most tools mounted on the main pivots, it is attached using a small brass pin directly fixed into the aluminium liners surrounding the scissors layer. This construction is more fragile than standard Victorinox tool mounting and damaged or broken examples are relatively common.
The origins of the Long Nail File go back well before the modern Officer Knife platform.
The first known appearance of the tool dates to 1942, on the 84 mm 247k, where it already serves as a dedicated grooming tool integrated into a compact civilian-oriented configuration.

Following World War II, Victorinox increasingly expands civilian-oriented features across its catalogue.
During the period of post-war structural refinement, the Long Nail File is introduced to the 91 mm Officer Knife platform through two dedicated models:
- Climber LNF (245)
- Huntsman LNF (246)

As Victorinox transitions from military supplier to civilian consumer brand, tools associated with everyday personal use become increasingly important. The Long Nail File emerges directly from this context.
Long Nail File Variants
The Long Nail File evolves through three main versions, each reflecting broader structural changes within the Victorinox Officer Knife platform.
First Version — Pre-1957
The earliest 91 mm Long Nail Files feature the small old-style nail nick
This version belongs to the early post-war period, when the Officer Knife still retains many pre-1950s construction details.
Second Version — 1957–1968
Around 1957, Victorinox introduces a redesigned Long Nail File featuring a large nail nick
The modification is primarily visual but improves access to the tool.
This period corresponds to the golden age of the Long Nail File within the Victorinox catalogue.
Third Version — Post-1968
Around 1968, the Long Nail File undergoes its most significant structural change.
The nail nick moves to the opposite side of the tool
This modification is not cosmetic.
As Victorinox transitions from the traditional bail system to the modern keyring, the entire LNF / scissors layer shifts toward the opener side
This prevents interference between:
- scissors
- Long Nail File
- keyring assembly
The relocated nail nick is one of the easiest ways to identify late-production LNF models and reflects the broader structural reorganization taking place across the Victorinox range during the late 1960s.
Models Featuring the Long Nail File
Only five known catalogue models carried the Long Nail File as a standard feature on the 91 mm platform.
One of the simplest and most elegant LNF configurations.
The Climber LNF combines scissors and grooming functionality without increasing layer count, creating a particularly balanced everyday carry model.
The Huntsman LNF extends the concept into the outdoor category.
By combining scissors, a wood saw and the Long Nail File, it bridges civilian refinement and outdoor versatility.
The Cadillac represents one of the most prestigious expressions of the LNF platform.
Combining the Long Nail File with the technician screwdriver and metal file, it embodies the highly specialized and technically ambitious Victorinox models of the 1950s and 1960s.
The original Champion platform places the LNF at the very top of the Victorinox catalogue.
As the flagship of the 1950s and 1960s, the Champion combines the Long Nail File with tools such as the fish scaler, metal file, wood saw and scissors, reinforcing its role as a complete civilian flagship rather than a purely utilitarian knife.
This special run Brown Boveri Cadillac combines:
- Long Nail File
- technician screwdriver
- clip point secondary blade
Like many high-end corporate presentation knives of the period, it demonstrates how the Cadillac platform served as a showcase for both technical and luxury-oriented Victorinox configurations.
As a reminder, Brown Boveri was the Swiss engineering company selected by Carl Elsener II in 1931 to install the world's first fully electric industrial heat-treatment facility at Victorinox, making this special run a particularly fitting historical association.
Disappearance of the LNF
The Long Nail File gradually disappears during the 1970s as Victorinox shifts toward more utility-oriented tools and increasingly standardized configurations.
Its story does not end entirely in the 1970s, however. A small number of Climber LNF (245) examples are known from the 1980s, suggesting that Victorinox briefly reused remaining Long Nail File components after the tool had officially disappeared from the catalogue.
Today, the Long Nail File remains one of the most distinctive hallmarks of high-end Victorinox models from the 1950s and 1960s.
Conclusion
The Victorinox Long Nail File (LNF) represents a forgotten aspect of the Swiss Army Knife's identity.
From its first appearance on the 84 mm 247k in 1942 to its final years on flagship models such as the Champion and Cadillac, the Long Nail File tells the story of a Victorinox era where grooming, elegance and utility still coexisted within the same knife.
Although the LNF itself disappeared from the catalogue during the 1970s, part of its philosophy survives today. The modern Compact still incorporates a small nail file on its multipurpose hook, preserving the idea that a Swiss Army Knife can be both a practical tool and a discreet personal grooming accessory without adding extra layers.
In this sense, the Compact can be seen as the last heir to the gentleman-oriented Victorinox models that once carried the Long Nail File.
