For me, I wouldn't buy this tang for $30. It looks abnornal. If I did not know that it was a hybrid, I would think that it went through some sort of disease or was once badly injured.

I guess beauty is in the eye of the beholder....or in this case, whoever buy this tang just have a lot of cash and like to collect rare items.
