Prior to 1961, Victorinox Swiss Army knives had a larger awl with no sharp edges. It was originally designed for cleaning the end of a rifle, and had no drilling capacity like the modern Victorinox awl. This tool is sometimes called a reamer.
In 1961, Victorinox replaced the vintage awl with two different tools-- a small awl on the red-handled officer models, and a reamer on the new aluminum alox Soldier model.
Uses: The original tapered awl was designed mainly to clean out the barrel of a rifle. You can also use it to enlarge holes, or to punch holes through soft materials.
