Great pics and videos!!! How did the parang work after you profiled it? What did you use to profile, and what geometry did you use?
It looks like they all have a place now

to me it seems like the grail in the chopping category would go to MOAB #1, #2 & 3 then tie but personal preference between the TTKZ and MOABOLO, then personal preference between NMFBM, Boom Parang, 1311, and B11, Then I am kind feeling like the 3 rd group (which by no means are slouches, just simply edged out) would be the NMFSH, Battle Saw, 1111, ASH-2 and so on...
I think it would be safe to say from user reviews that the battle saw in my opinion prior to use would fall towards the bottom of group two or top of group three, HOWEVER, after seeing the notching, makes it a force to be reckoned with if you really ever need to build a shelter. I think it would be great at chopping but after extended use, may quickly become tiring vs others like the 1311, Boom Parang. It seems like the Battle saw would be a much better user with a FSH type handle, but would that affect its mechanics in the saw format? Just a thought, maybe an upgrade for the future
Not sure about the top three through all-day endurance. Seems like a lot of weight to use all day. I really have zero working experience with them so this is pure speculation.
