Technical but not exactly IT
Oh, and it's not mine either.
Canford Audio sell an earth spike fitting tool and the description goes thus:
"Earth spike fitting tool. British made, using heat treated, drop forged, shot blasted, polished face steel heads with genuine hickory handles, these specialist tools will ensure correct fitting of most earth spikes, as well as performing numerous fine adjustments generally required at outside events. Weight 1.8 kg"
As you may have guessed, it is in fact a 4lb lump hammer.
