blad replacement under warranty is free, that said if you break or want a new blade it is 30.00 I just sent one back to have a blade replaced, went out yesterday I don't know if it will be warranty or cost but for a new blade I will pay 30.00, I cant buy another zt for that. something was wonky on the ht I think it was s30v and my cheaper kershaws held a better edge. I sharpened it 4 times and never got the edge my other zts had. I own 5 now and have owned over 25 so one bad blade out of 25 aint bad. the part about warranty on whether a blad is replaced free or not is confusing to us but probally after this blade is done I will have a better understanding of how it works. it could have simply been a bad run of steel. I don't think I have ever saw a blem down as much as 1/2 price though in the zt's the kershaws may have been though. I would keep check with dave he may get something in you want. of all mine the 0777 is my favorite with the0770 a second, the 0777 is a wall piece to me the grail of knives. I refuse to carry it the 0770 however while smaller is my edc now. I cant post pics here but the 0777 you see at the top of daves site is almost exact to mine. I have been offered much more than I paid for it and it will be mine until I die.dave has a 0300 listed I think I saw one there, if your friend paid full price he probally would get as good a deal from dave and you wouldn't have to worry about it being legit or not. I have bought knives from him and would recommend him to anyone.
