Considering buying a Griptilian and was wondering if the Cabela's D2 versions are worth the extra money over the 440C versions? I have read that BM does a good job with the 440C heat treat before, but don't know how true that is. I know the 440 is more corrosion resistant, but does the BT2 coating on the D2 blade make much of a difference in it's resistance? I know where I can get a Rescue Hook/551 plain edge combo in 440C for 78 bucks. Knife's going to be used as an edc. Any info appreciated.
