If I am not correct please let me know but I think 154CM is the toughest steel Buck currently uses. I think Buck should make the 124 Frontiersman out of 154CM, keep the Micarta (could change up the color options) and improve the sheath by a wide margin and you have the super knife the 124 could be. I like it as is but if you can make the car run alot faster, why not soop up the engine. Or they could go back to 440C, and to be honest I would love a throw back 124. The custom shop would be all over this if Buck did not want to do a full run.
