All the ZT's are great knives. I wanted to carry them as a dealer and talked direct to Kershaw. I found out if I placed an order it would take about 24 months for them to fill my order. I also found that right now only one guy is making all of the ZT knives and he only does that when they can free him up from his regular duties. I was told they are looking to expand production by putting the one fellow on them full time and adding a trainee. They told me the only had one veteran employee in mind for that slot. I was told they are so series about the quality of this line they will only consider letting their very best people build them. Right now that's just one guy. So you can figure the quality is pretty consistent.
I here the knives are very durable and are capable of very tough tasks, including hunting, fishing and there are primarily used in law enforcement. There are a lot of articles and blogs that talk about these knives. I found a blog that reviews zero tolerance 0350 knives you can take a look and see what you think.
