Question: how much carbon is in the steel blade?
Document: When I got this sword it was clearly not new it has some scratches on the bottom and the Half chain link is not on the end of the chain I was very disappointed when I saw this he stated this was a new product and it's clear that it is not
Overall I got exactly what I wanted, this sword is not for cutting or combat, it's for display and cosplay and it's really fun to just swing it around if you&#34;re in an open space, if you want good quality 68&#34; sword this is it.
Just got this sword and I love it. If you want show accurate replica then this is not quit it, the 50&#34; one is more accurate in size but I wanted to have long and cool looking sword that would amaze everyone who would see it. The sword is made in China and the quality is better than I expected especially after reading other reviews.
I thought that i will received something magnificent, something that will amaze me.. the truth is the sword is too heavy, hard to open, hard to handle and many more.. i hate to say it but the manufacturer should learn more lesson by the expert about how to made a sword such as united cutlery, kit rae etc.. your product was suck! !
Answer: no
