I can't say as the above knife, but I do like the advice on the CRKT page, which is similar to what I was going to say about one of the easiest ways to know what you are buying is to physically be there when you buy it.
The point they make about "street price" I think is fair - as has been explained at length at other times on this site, the process for developing a "MSRP" can be a bit silly and can make it hard to "track" the "real price" of something. If MSRPs were set realistically (and not so department stores can offer "60% Off!") people doing their research and looking to purchase will be less tempted by the "risk" of great deals on certain sites. (this is also why I only buy knives, or various other products, at two or three points in the year when local retailers are stocked for volume sales and their prices drop accordingly)
Buy from a reputable dealer. If you buy a CRKT® product from a reputable retailer, whether cutlery, sporting goods, hardware or department store, or a known internet retailer, you can be sure that you are receiving a genuine product and that the retailer and CRKT® will stand behind the product. Your purchase of the new CRKT® products will be covered by our appropriate warranties, including our excellent Limited Lifetime Warranty on new knives.
Consider the price. If a price for a new “CRKT® product” seems to be too good to be true, it probably is. Unlike some manufacturers, we set our Manufacturer’s Suggested Retail Price (MSRP) recommendations at very competitive levels. So we don’t anticipate that a quality CRKT® product will require a much lower “street price” to be a great value. If you see a new “CRKT® product” on the web reduced from $79.99 to $19.99, an alarm should go off. This is very likely a knockoff, and not a genuine CRKT® product.
