Great info Kronckew

,
trench made knives and daggers fabricated 'in field' were very varied. Made for use, in what was known as 'trench clearing'

the majority I have seen tend to be stabbing impliments, with simple needle/stiletto blades. Easily made and effective.
What struck me about the 'knife' which started the thread, is the deliberate curve of the blade. It seems idealy suited for slashing, and with a shortish blade suggested it may have required some skill to use (if it is indeed a weapon). I was thinking it may have been used in a similar way as the Indonesian Karambit, perhaps in pairs, one in each hand (been watching too many martial art films I suppose

)
I suppose this could be a tool, but seems to small for an agricultural tool (although I believe the Karambit started life as a 'crop cutter') or effective as a wood working tool.

Having said all that, I hope I'm not going down the 'same road' as I did with my 'deadly' Asparagus Spear.....eh Kronckew
