This will be my first khukuri. My inclination is to go with either the WWII in 18" or 16.5". Perhaps also the Ang Kola in 15". I really want the blade to be a good all around utily blade, but I also believe a blade should have good combat applications. Thus, I lean toward the 18" WWII. But will this be too big for backpacking? I will not be doing any unusually heavy chopping with the blade; I just want something to tote around when I'm out and about, so to speak. Any input would be appreciated. Thanks.
