Matt,
In my area I use the machete for off-trail travel, clearing campsites, and shelter building in the lower elevations. If you hike up out of the low lying forests you often have to dig for water. I have the habit of testing the ground with my machete blade to see if the soil has enough water content to bother digging. I also use the blade to do the digging. So far I have only ever done this with inexpensive Tramontina (Brasil Standard) blades that only cost $3-$5 US. I treat them as disposable and when they are too gnarly looking I give them away.
The Valiant Survival Golok looks like a great blade, I saw that same review. Still I'm looking at that $13.99 offer from Brigade Quartermasters. It just has "Beater Blade" written all over it. Mac
