Thanks Mr. Fowler for your input and making an blade that will hold up no matter what. Indeed you gotta test them out before they go out.
Two days ago I forged myself an blade, and after the temper cycles I used the horn of my anvil to beat the hell out of the blade's spine. It is an good sized 6" blade that is differentially tempered and all calamity that the blade came away with is slight mushrooming as Mr. Fowler described. Easily sanded away if it is visually an blight.
Indeed Mr. Fowler is correct in that the blade must be counted on absolutely.
Of course an heavy stick will provide for an more comfortable and efficient baton than an rock, but hey, sometimes an rock may be all than is availible. If the blade I'm carrying wont survive from an bit of rockage than it's time to get an new blade.
While hardrock mining I carry an RIGID made 10" rap wrench. It gets used for all manner of extreme and unholy duty in an very harsh environment. In an outside environ I view the blade in much the same way. It's an tool I carry for tasks to accomplish. If it is an tool that won't hold up or cannot be used for real world work than I really don't need to be carrying it.
Life is short, use those tools gear you own as when you die it'll be sold off or inherited by someone who really won't appreciate it anyway.
