Subject: The Restoration of Old Rusty Tools and Vintage Edged Weapons

Most households have old steel tools and various steel implements lying around, such as old axes that have seen better times and have undergone corrosion. The surface corrosion is often due to storage of the steel tools under conditions where moisture is present.  Surface rust on the steel does not necessarily detract from the purpose of a tool but it is unsightly and need not happen if good storage conditions are available.

The methodologies that are used to remove surface rust and restore the steel tools to a pristine working condition will be described. The restoration technique used may be simple or complex, depending upon the extent of corrosion damage on the steel.

Another field where restoration of corroded objects is carried out is the refurbishment of vintage edged weapons, more commonly called bayonets, for military rifles. The presenter will show how he has restored a collection of vintage bayonets from World War 1 and World War 2. Many of these vintage edged-weapons, collected from around the world, represented stateof-the-art material selection and engineering design in their era. The restoration process also includes the leather scabbards and wood grips on the hilts. The bayonet collection to be shown originates from the 1880s through to the 1940s and the history of each weapon will be outlined.
