I own several brands and types of machetes. I have 18" Ontario, 18" tramontina, 18" cold steel bolo, a Woodsmans Pal, a 12" and 15"Cold steel kukhris. The Ontario and CS bolo are good for light to medium chopping. My tramontina is a POS. The blade chips with every swing. The Woodsmans Pal is more of a hatchet than brush clearer. I have never been able to get the blade to take and hold a good edge. I have been told I may have gotten a bad one because they are held in high regard by those who use them.
Far and away my most useful and favorite is the Cold Steel 12" Kukhri. This thing out chops anything I have come up against. It will hold a hair shaving edge after clearing a trail or chopping kindling. The 15" has a little more power but is unbalanced. My 12" kukhri goes with me every time in the field. i bought it as a "second" from Cold Steel for about $50. No regrets.
