The Reamer is present on many Victorinox models. Historically the tool started out as an Awl, some people still refer to it as such, but Victorinox is currently referring to it as a Reamer, Punch. In 1961 the Awl was redesigned and given a sharpened edge, making it more suitable for use as a Reamer. Typically the tool is located on the backside of the knife and may include a hole through the blade known as a Sewing Eye. The current (2008) 91mm backside version extends 37.7mm, with a sharpened edge of 22.8mm.
The Reamer has a hardness rating of RC 52, but it is not known if this applies to all versions if the tool.
There are currently three versions of the tool in production. The basic variation is with, or without, a sewing eye. The third is a version included on the Alox scaled knives.
91mm Vintage Awl
Alox 93mm Version
|The Alox scaled knives don't have backside-tools, so the Reamer is on the front-side and shares the layer with the main blade. This variation has a distinctly different shape/design with a more pronounced taper, and right angle bend at the top edge forming the spine of the blade. This bend aids in reaming of some materials and also serves as a catch to open the tool, rather than the typical nail-nick on the side of the blade. This version does not include a sewing eye and is the shortest, but it has a sharpened edge of 29.9mm, which is longer than the 91mm version. On many materials this version is actually the most effective, or efficient, reamer. Note: this tool is also included on the large 91mm collector knives the SwissChamp XAVT and the SwissChamp XXLT.|
|The discontinued 108mm version of the tool really is more of an Awl, and does not contain a sewing eye. The tool is slightly longer (48.6mm), more pointed, and has a slightly less sharp edge.|
The Wenger tool is most often closer to a regular Leather Awl without any sharped edges.
Mike Horn Version. This new version that first appeared on the Wenger Mike Horn Ranger model, is quite unique. This tool has a cylindrical design that has a sharpened edge and works well for drilling/cutting holes in wood and softer materials.
