I saw a Youtube rope test video between the two blade steel's and I tell you what. I am not seeing a huge difference that would justify the cost difference between the two. Sure, there is a performance difference I can see that but to justify that much in cost difference? Bear in mind, I am basing the cost difference using eBay as a source since I don't think Spyderco no longer sells the Para 2 in m390. So, eBay would really be a poor choice cause their prices are all over the map. Not really sure what a fair price would be for a new Paramilitary 2 m390 would be?
