I have an old crkt m-16 that i decided to start using the other day. I couldn't remember what type of steel it had. So I emailed customer service and asked, while i was at it i mentioned i had managed to lose the pocket clip. My experience with customer service from all companies has varied greatly so I didn't expect much. In less than 24 hours I had an email from Linsey Phelps in which she answered my question regarding steel {aus 6} and further advised If i sent her my address she would get a clip and screws right out to me, free, Yes FREE. Dang boy I love free. Anyway I was very pleased with the service and thought I ought to post it. You always here about the unreturned phone calls and unanswered letters but you often don't hear about the very good service which pops up now and then. I was going to get a knife this week now I may very well get another crkt just because of this, although I'll need to watch out for steel, hate aus 4. Well I'm done, ahgar
