I recently was gifted an FDE PM2 with DLC coated S35VN. Perhaps I am underestimating S35VN, but this steel seems more common than 20CV or M390 but both of those sprints are cheaper than my FDE PM2. Can someone clue me in as to why? My version seems more numerous as there are still specimens available. So, it doesn’t appear as though rarity is dictating cost. I’m just trying to understand how the steel equates to cost if that’s at all involved. Thanks ahead of time.
