Hello there peoples, I just got his couticle that i ordered from an english company, I think it's going back though because of damage, although im new to this so im trying to figure out what to do. There is an obvious bad edge on the left side of the stone and a piece that has obviously been glued back on, any comments on the severity of this? Looks pretty bad and seems a waste to put a razor near it.

Also the couticle has thes red lines running through it, I was wondering are these a bad sign on a yellow couticle and would this meanthose lines would make it a bad hone?

Anyway i made a video so the stone could be viewed...
