ok think about this. after shooting 3 x 4 elk i went to town with my lan-cay m-9 bayonet on certain aspects of elk field dressing.
when i received m-9 it had a nice edge from factory. nothing to write home about and you sure as hell werent shaving w/it.
i took my diamonds and started with fine then moved to extra fine. 22 degrees jes lak slicing some cheese.
anyway in very rapid time its edge was gone trying to cut hide away. this is normal for a high rockwell hardness blade. the m-9 is a everything knife. pry this pry that, hammer on it etc. therefore it needs high rockwell to survive its appointed duties.
after m-9 blade started fading away we then moved into elk with stanley box cutter blades. these lasted better because of their ability to HOLD AN EDGE vs the m-9.
now lets pry open an ammo box with yer wifes henkel set of knives. sharper than hell and you can shave with them. buttttttt..........when you pry open ammo box the blade breaks in 2. the m-9 with the dull blade prys open ammo box no problemos.
so the higher the rockwell hardness the edge is not going to last as long.
another example. hk g-3(hk-91) bayonet. once again high rockwell. has bloodlets same as m-9 bayonet. SOLINGEN STEEL! the best there is. you can go to town putting an edge on it, but you will never shave with it and if ya cut open a few cardboard boxes the edge you just put on with be duller than a butter knife. the tip will remain pointy and it will hurt if stuck with it..............but you aint cutting elk hide away from meat with it very long.
another example: buck 6" blade, black handle black leather case model. you can put an edge on that knife that will last a fair amount of time. you can bash a deers pelvic bone with a rock and it will take it. try the same on an elk and you are asking for it to break due to thickness of pelvic bone btwn the 2 animals.
there is no perfect knife that is a multi-functional tool. cut meat you need it sharp. break bones/pry open ammo boxes / cut hide etc. you need a different knife.
a bayonet is the middle of the road to do everything. thats how there designed. it aint the best but it will do and you can resharpen it and thats why they include stone attached to scabbard.
