I've owned and used a variety of "chopper" knives, as well as some 12" machetes. I've found that I do not like the amount of force necessary to make a short blade chop - it uses too much energy and causes the blade to sometimes want to glance off of what I am chopping if I get the angle wrong. This can make for a nasty injury.
My "go to" is a 16" Condor Speed Machete - it will take down grass, twigs, small limbs & other brush with a flick of the wrist, but will also easily cut down small trees if I use it properly. It also costs a quarter of what TOPS wants for what I consider to be an inferior tool in terms of performance.
If I were really tight on funds, I'd grab a Tramontina bolo or 16- 18" machete for around $12 instead, but I really love that Condor. It's worth every penny that I paid for it and then some.....
There are some TOPS knives that I really like, but this one ain't one of them....
