History
The Handyman was introduced in 1973, around the time the model number format changed, and model names were standardised by Victorinox.
Its original toolset (fish scaler not pliers, no chisel or hook, original fine screwdriver) was equivalent to the old six-layer Champion a (with the exception of the long nail-file), which had been semi-retired following the introduction of the seven-layer Champion in 1973.
The pliers were introduced in 1986, replacing the fish scaler.
Its evolution followed a very similar path to the Craftsman, with tools and tool versions changing as the Victorinox tools evolved. The Craftsman page outlines some of those differences.
