I recently ordered a bokken online, and what arrived was
a) quite light, and
b) laminated.

I would be more concerned about the latter than the former,
especially if the bokken is going to be used for kumi-tachi
(sparring). I would suggest that you check the bokken carefully
before each training session for cracks, splinters or other signs
of potential failure - but then, that's good practice anyway.

Hope this helps -
