I am suprised by your comments in regards to the Tramotina Bolo. I had one, and was very unimpressed.
The steel was very soft and thus very prone to impact damage. As an example, I was clearing some shrubs and
vines out of the fencing in my backyard (standard cyclone fence), I was basicly just swiping the bolo along the
fence surface, taking out any branches and vines. I'd have to stop every three to four minutes and hit the edge
with a file. The spots where the edge contacted the fence (which is darn soft metal) were heavily impacted, but I
was not being very careful and there was a lot of lateral pressure applied to the edge....... I hit a nail sticking out
of a wooden fence post and it caused a large dent in the edge, basicly large enough that repairing the damage
would take more time than the bolo was worth. Last time I saw it was in my ex-wife's garage......
After blowing out the Tram, I switched to an Ontario machete (USGI 18") and the results were much better.
The Ontario kept its edge for the 45 minutes it took me to finish, and was easily sharpened using a DMT course
diafold and then a ceramic rod. There was no damage (though I was also being more careful with my swings),
and its not like the Ontario USGI machete is a high performance benchmark......
