Your weapons are really beautiful, but as a martial artist I'm put off by how light they are. I'm not saying that LARP weapons should be as heavy as real ones (that would be overkill) but a bastard sword (which is wielded in two hands) needs to weigh more than 450g.
Such a light weapon feels just wrong and encourages just waving about the sword instead of swinging it. A weapon should always suggest the wielder to hold something of consequence. Also, heavier and still balanced weapons make for a more beautiful and realistic fighting style in LARP.
Please consider at least doubling your weights, or adding it as an option.
Are you aware that Calimacil weapons weigh a lot more than every other weapon manufacturer?
There is quite a few people that think they are too heavy...
