Question: is this sword functional?
Document: love this sword! just like the anime and it is full tang.
i love this sword it sharp cool and it makes me feel like a badass every time i hold it
this sword is not tensa zangetsu its just zangetsu, the tensa version is the thing long black one with the chain off the hilt
this sword is just perfect weight height texture material my friend died when I got it for him a must buy GET IT
This sword has some nice weight to it yet well balanced. I use it two handed & it gives me good leverage.Very intimidating
But the blade's color is sort of warped in some places, but it's not too bad. It's a cool sword, but if you're really looking for something serious, you might want to reconsider.
this sword is amazing however the white wrappings around the handle were coming off a little when i got it but other then that it was perfect!heavy, sharp, big, looks just like it
even tho it was made for looks and not play this sword was able to deliver, loved cutting bamboo with in in the back yard untill the handle broke off
This sword is beautifully designed. It captures the way it looks in the anime. From the two tone blade down to the cloth wrapped handle it is a great sword to have for any collection.
Great cosplay sword not an exact match but worth the money. If you want the real deal with any of these things better forge it yourself otherwise this is the way to go.
