The Long Nail-file (LNF) is a bottom mounted nail-file with a small nail-cleaner tip, that is also referred to as the Manicure Blade. It is fairly thin and narrow, a nail-nick is located near the end of the tool, that is accessed through a cut-out in one of the aluminium liners next to the tool. When it is folded into the body of the knife, the outward surface of the tool is smooth with the file surface on the underside, so it is very easy to not notice this tool when it is folded up.
All Victorinox and Wenger versions discontinued.

This tool appears in early 1940s catalog pages, usually on the smaller 'Gentleman' and 'Ladies' series of models, such as the 75mm Accountant-style models. The 1967 Victorinox catalog shows the long nail-file available on the 91mm Champion and the Huntsman. The tool is also found on the earlier 84mm Golfer (from 1977 to 1999) and the older 84mm Small Climber, some of these models will have had the early Victoria tang stamp. However, there must have been models made into the 1980's with the long nail-file, as it has appeared on fairly recent 91mm models such as the Compact and Climber. Also, Climber models (in very small quantities), issued as late as 2010, (with the newer SWISS MADE tang stamp) have been seen with this tool, these are likely the last models produced containing the long nail-file, using spare parts from inventory.
If present in 84 or 91mm models, the LNF is usually mounted on the back of the knife, in the same layer at the scissors, pinned into the soft aluminium liners surrounding it, with a small brass pin, (compared to the regular tools that are attached to the structural rivets). If the LNF is present, the scissors are switched to pivot from the top (main blade) end of the knife, as opposed to their more common/normal bottom-end pivot. The mounting for this tool is somewhat fragile and is more easily broken than for most other tools, break-offs are not uncommon.
Models that have this tool intact, and in good condition, are highly valued by collectors.
A very uncommon tool is a wide version of the long nail-file that was included on some 84mm stainless steel and horn-scaled models in the 'Gentleman' and 'Ladies series, as well as some Cellidor models. The wide version is two tool layers wide and covers the entire back spine of the knife, completely hiding the springs. It was given a mirror polish on the luxury models. The tool is very slightly tapered and varies in width from ~5.5mm at the pivot to ~5.35mm just before the final taper for the nail-cleaner tip. This compares to ~2.6mm to ~2.40mm for the narrow version.
Wenger has not manufactured this tool for a very long time, and it only featured on one or two older vintage models.
