Fairbairn-Sykes.

Fairbairn-Sykes with Knuckle duster attachment. A strip of steel with rivets through it has been attached between the pommel stud and a new cross guard

Middle East pattern Knuckle Duster an exceedingly uncomfortable blade to use, the blade is held by your fingers and not your palm as in a normal knuckle duster, this does not make the blade secure in your grip.

Rogers knuckle duster. This is a traditional pattern knuckle duster and is very comfortable to use.

USA

Fighting knife, this was used in the US by my father as a knife while in the scouts. The swastika markings are American Indian luck symbols and not the NAZI logo, this makes me think the blade is pre war. Similar to the K-Bar knives made by Kutmaster
