Founded in 1973, in the Province of Québec, Canada, by the late Swiss-born Josef Elsener, a prolific inventor, whose family lineage included the designers of the Victorinox Swiss Army knife and Lesley Rust, with a background in theatre administration and advertising, Proparms became Canada’s leading special effects weaponry and specialized properties company.
In 1978, Elsener designed the 20mm Neutrex Waterjet Disrupter for the Sûreté du Québec which Rust and her close associates later introduced to the wider North American and global markets, together with specialized ammunition and projectiles and a wide range of EOD/IEDD tools.
