In a bit of an OCD episode I just had, I decided to put together an Excel table of various PM2 and Para 3 offerings based on handle color/material, plain or DLC coated blades (or "other" in two cases of the upcoming 2018 Forum PM2 and that crazy REC PVD Para 3 that I’m still in disbelief how much it’s appreciated in value!), and steel type, along with the various model numbers. I of course could not have done this so quickly without Spydiewiki! :D
I hope it’s useful to track what combos have been done so far and what is still available. What’s interesting is that certain dealers don’t necessarily lay claim to their own color G10 for both the plain and DLC versions of both models - like the situation with red and orange handles (DLT and St. Nicks vs Jeff at the Cutlery Shoppe). I’ll try to keep this thing updated and pretty it up a bit, but I figured someone out there might appreciate it! Cheers, Radioactive :)
