I used to be a big CRKT supporter but, not anymore. Their QC is just lacking. Especially at the prices they are asking for most of their knives. With that being said, I admit the M16/21 series is very popular. I own an M16-02 myself. Also own a Marzitelli Prowler, one of my all time favorite knives even though the blade steel is poor.
For the money CRKT is asking, you could do much better than most of the products they offer. Do yourself a favor and keep looking at other brands.
