I've trained in "close combat" with the US Marines, US Army Paratroops, US Army Rangers, US Navy SEALS, and British SBS (and their Australian counterparts), as well as with such stunt luminaries as Anthony DeLongis (btw, my invocation of those groups and individuals does not - and should not be construed to suggest that they agree or share my opinions - they are offered solely as an assist for judging my competence and the basis of my comments). That said, as a combat tomahawk, I consider the M48 design to be, far and away, the best - the SOG option is not even in the same class. The SOG blade form does offer a few advantages in a utilitarian mode, but it is deficient as a combat weapon. I keep two edged weapons (if you don't count my "Leatherman", which should be on everyone's "always carry list") in my "combat load" - one is a Ka-Bar style fighting/utility knife (again, far superior in almost all roles to any other general purpose knife) and an M48 (where weight and mission considerations allow). I've not had cause to change that basic load since the M48 came out. I have yet to find a decent machete which does all that I require, but I noticed that "Sportsmans Guide" offers a "cane knife" which comes close. It would take relatively little change to make it a truly competent all-purpose piece of survival gear.
