Hi, Does anyone know what steel Buck used on the 3 dot 1980 112FG, it doesn't look like 440C, I know that Buck used 1980 112 blades after 1980, but I'm not sure of the steel, I think the .112.. had 440C in 1980 like the 110, I know it can't be 420HC but it looks like it, it's flat to the edge, maybe 425M? the tang looks blanked not machined. Thanks George God bless
