I have a Philippine BOLO.  My (ex) father in law gave it to me in the mid 80s over there.  It was a better deal than that daughter of his. He said it was made from a leaf spring of a bus.  It is crude, I have never sharpened it. The spine profile is fairly thick and it quickly tapers to the cutting edge, so it is very wedge like blade.

It is an excellent wood splitter.  Rarely need to mallet it past a knot.
I saw relatively short lengths.  Packs easy.

I've noticed at campsites in the last few years, there are remnants of a lot of  people that don't know how to, select wood, (i.e. either green or big enough to make a dugout aircraft carrier) or prepare wood for combustion.   Too many sites left with 20foot chunks of punk birch, that JoeSchitt the firescientist was going to meter feed into the fire.
Rant over...

It's been a great paddling summer and fall looks even better... 8-)
