I currently own a 2010 amber bone CV model Trapper lock. To get to the one I currently own I went through three others. I started off with a 2008 stainless model. It had bad blade play so I sent it back. Got a 2009 stainless model. It had bad blade play, so took it back. Looked through three others in store, and found one that seemed good. Got it home and it too developed blade play fairly quick. Traded it off. Then, I found a guy selling what he advertised to be 2010 amber bone CV models on the sales site. I ordered one. The first one he sent was in fact a 2009 model and it had bad blade play. I sent it back, told him to send me a 2010 model. I received the 2010 model and it was very nice. No blade play at all. And, I've had it over a year still with no blade play. It's a nice knife, and has developed a nice patina on the blade.
Some other issues I have with the model is that the thumb stud gets in the way for me when I try to sharpen it. Makes it a bit of a pain to sharpen. The thick blade doesn't seem to cut as efficiently as the thinner flat ground blades. Other than those issues, it seems to be a nice knife. But, it tends to sit on my night stand, and not in my pocket. I tend to carry my trappers, and stockmen more often than the trapper lock.
