I just bought an Endura this weekend. I am new to Spyderco products, and am unsure of what this model is designed for. The clerk was young and quite busy, so I didn't bother to ask. How does this compare to the Police model? This was $59.00 at a sporting goods store. I like the knife, very sharp and has a smooth feel to it. I'm noticing the price on this model is far below that of other similar models on E-Bay. Is this an inferior knife, or not built to last as well as the Police model? I'm just wondering about the low price?? Any thoughts or comments? Thanks!
