Ive got a Fairbairn - Sykes 3rd pattern fighting knife made by J Adams of Sheffield, one of the MOD contractors
This isnt my knife btw, im getting the blade professionally reground, but its the same model.
Its early 60s, RMC issue.
Notice the blade, 7" double edge with a very sharp needle point. thats for precise puncture of the ribcage, arteries and vital organs.
The knife dissasembles into 3 main components. The hex nut on the pommel disassembles it. The blade, which goes conpletely through the handle via a small square slot running though the handle, the handle itself, which is 8oz of solid brass makes a last ditch emergency cosh if the blade breaks. Finally the cross guard.
Its a killing machine. A pure fighting knife.
