Did you specify a D2 model? If you did, return and get the right one or your money back. LT has been putting out some models with different steels, but I too thought this was a D2 only model. Frankly I'd be disappointed, as I much prefer D2 over A2. To each their own. It just depends on whether you personally are satisfied in the end. A2 is more prone to rust, if a little easier to sharpen. However that ease of sharpening translates , to me, into a blade that doesn't hold an edge as long, something I'm very fond of in D2.
