Does size matter? Question to jambiya lovers

[motan]

This is getting too personal, so I am going to stop here. But before that, I want to repeat what I said before. Anything that is large enough, sharp enough, not too heavy etc will do. There is no need for sophistication, only for user skill. I also said that I would personally prefer a heavy stick, baseball bat etc to a dagger.
The reason I say this is not because I want to dowplay the value of beautiful daggers, but emphasize that reasons related to function is not productive way to explain the shape and size of daggers (see recent thread about fullers). They are like they are because their makers and owners liked them that way. After all, most of us, I think, are antique collectors and not would-be knights...
