Victorinox Signature 1 Classic - Houghton International, a British electro mechanical engineering company operating globally in the repair, maintenance and life extension of rotating electrical machines. Its primary market sectors are power generation, renewables, industrial, water, oil and gas, marine and rail. This Signature 1 model has a removable ink pen insert to use separately from the knife. While I still see advertising Signature 1 models still being made I have yet to find a supplier for the ink pen insert by itself.
