Military standard issue knives, are generally speaking nothing out of the ordinary (Some exceptions). They are cheap, practical, reliable but must also conform with the standard dress code sized blade. During my time in the service I was issued a few blades, My first in the Australian infantry (Combat medic) was a small multitool which honestly was a piece of crap followed by the M9 detachable bayonet which fits with the standard issue AUG's, truth be told it was nothing special but then again it was not intended to be a high quality survival blade. Later on we were issued m7 Bayonets they were essentially the same as the M9 but for the M4C rifles. Both of these bayonets got the job done but given the choice were not the blade for most troops. During my services in Iraq in the SASR there was a limited issue of a Spyderco blade the exact model I never bothered to find out, that blade has to date never been used.
In a recent deployment's to Afghanistan, Timor and the Solomon Islands I took a falkniven a1 and fallkniven f1, I had no trouble with either one they got the job done in almost every situation they were needed for. Besides using friends I have never owned a Busse or seen any issued (at-least in Australia) But I am considering buying one.
I doubt this has been much help but I hope I shed some light on military blades.
