I have to share this story I heard today

By the mid 1970's, the once-great Sheffield cutlery house of Joseph Rodgers, despite having taken over its long-term rival George Wostenholm (IXL), was on it's last legs, and was first bought by the relative newcomer Richards of Sheffield, and then in turn by Imperial. The move to the Richard's factory was not popular with the Rodgers-Wostenholm cutlers, and possibly even less so with the Rodgers management, if indeed there was a place for them at Richards at all. They still held loads of the old Rodgers and Wostenholm stock, from blades and parts to finished knives, but the cutlers were simply told to "Get rid of it" by their old gaffers, and the nearest place to dump it all was in the River Sheaf, which ran next to the factory! So out of the windows it went!

News went round, and a few handfuls of penknives were rescued, but some of them may still be rusting away in the river, or were washed away decades ago
