I was wondering whether Buck used two different 154 steels on the Gen5 Skinner (I know they also use 420HC on this model). On the Buck website I noticed that they offer it in CPM154. However, on online retailers, some seem to have it in 154cm. Is this a mistake where they should all be advertising them in CPM154 as stated on Buck's website? Or did Buck make two batches...some with CPM154 and some with 154CM. Thanks.
