I said I picked up Sephi's sword, and yes they have made both,...though on review the replica Masamune is indeed heavier than the buster sword by 3 pounds...Here's what it says on the website where you can order it. (the buster sword isn't as durably made though...)
"...After a much anticipated wait...it has finally arrived....the OFFICIAL Masamune Sword produced EXCLUSIVELY for Weaponmasters.com and measuring in over 6 feet tall!
This is one of the most spectacular swords ever produced with a blade so large it can only be THE MASAMUNE and a weight that is downright impressive! With it's one of a kind shape and design we are sure everyone will recognize this as the most famous Masamune ever produced!
All the parts of this sword are made of high quality stainless steel which makes this amazing weapon very durable and at the same time very heavy.
Due to the size of this sword a scabbard will be sold separately in the near future.
For safety reasons the sword blade is not sharp due to its sheer size and weight.
