The models look very nice already, I especially like the shape of the axe =) (though I have to agree somewhat on the thickness-debate

)
-The Katana is very cool with regard to the shape and tip of the blade, but here I too agree with Andrew, in that the handle is way too short.
-In my (not really professional

) oppinion there is something terribly wrong with the cutlass, however (don't take this the wrong way^^ i love the shape of the blade!): Look at the point where the blade meets the handle. The blade is two to three times as wide as the handle and that just doesn't work

I think in real swords the handle is really just an extension of the blade (they are ONE long piece!) with something wrapped around for a better grip. Not to be a realism-jerk

but try googling for "sabre" or "cutlass" you will find that the blade and the handle are always of the same width where they meet
looking forward to seeing more of your models!
cheers
