Phew!! Thanks for all the advice and info. After reading all your comments, I've decided I'll hang out for the Military......after spending a long time scrutinising the blades, I've re-considered and I think I'll go with the satin finish/plain edge.
Uses?? Mmmmmm - well, I live on a 100 acre property just out of Canberra (the capital of Australia) and you'd be amazed at the number of times I NEED a blade and I don't have one with me. This beauty I could keep with me at all times.
I'm sure I could probably get by with something less exotic (and less expensive) that the Military, but you know how it is when you see something that fills your eye like this does, and you just WANT one!?
