The following clasp knife sold on Ebay on 19 Feb 2009.
I have no reason to doubt the description. If it is correct, it is a wonderful little piece of history.
The description for the knife was :

WW1 AAMTC AUSTRALIAN FLYING CORPS AIF SOLDIERS POCKET KNIFE
Research reveals that 14258 Dvr W.M Stott ( William Mcgregor Stott ) enlisted 10/4/16 At Kadina South Australia and returned to Australia 12/7/19
Dvr W.M. Stott served in the 1st A.A.M.T.C A.I.F, and was later transferred to the Australian Flying Corps where he was taken on strength 7/11/17
Knife has been engraved by the original soldier (see photo's)

Knife has 3 functions to it
1: large knife
2: smaller knife
3: can puncher

There are no makers markings that I have been able to find or see

This knife does not comply with any of the known patterns of clasp knives approved for issue to British soldiers during WW1. I am only aware of a single pattern with metal scales, the pattern 9401/1917 Clasp Knife, and that designation has been attributed to a different knife.

There are two possible explanations for this knife.

• That it was a civilian clasp knife and entered military service as a "Private Purchase" item.
• That this was an "Owner Modification" of an existing issue knife either because of damage to the scales or as a "Trench Art" project to alleviate the boredom of life in the trenches.

If anyone has any information about any WW1 knives issued to, or used by Australian Servicemen or Women; please .
