Welcome, callahwj. You seem to have made up your mind, my opinion will not do much harm on you...
Many MA moves are based on agricultural or other most familiar moves like plowing. Getting familiar with a very much standard khukuri on daily basis will give you the sense how to make best use of a khukuri' as a khukuri because khukuri will tell you how a khukuri should do and how it shouldn't.
Well, if not me, HIKV will give you the chance to fondle one of that kind like 15" AK some near future. Have fun!
