Or, say, rock maple or walnut plywood (I have never seen either of those in plywood form though... its kind of unfortunate, those would be some darn strong materials). Actually, it wouldn't surprise me if the plywood used was made of birch... while not as heavy as maple, it is a bit heavier than pine, for example (and I think it is used in boats, so it shouldn't be that hard to come by).
