I have one, and it's my favorite machete for use around the backyard. I have a bunch of reedy/weedy "trees" that basically a super fast growing flowering shrub that spread and leaf out fast. Great for privacy between the neighbors but makes for some foliage that requires some aggressive trimming.
The bolo has just enough heft to cleave through the "wood" but fast enough to cleanly cut the willow-like switches that hang down away from the main trunk.
Anyway, my guess is that the lighter measurements tend to be more accurate. It's a tad stiffer/thicker than a more common machete shape, but they aren't bruisers. I'm sure there is a lot of variation in the specs, though. These are super cheap, stamped out blades after all.
