I can't help you with any of the Tramontina products, and what you want to do with a machete makes a difference. Do you plan on chopping your way thru triple canopy jungle, or just what to whack the occasional vine? I have a 12" machete that I brought back from Panama in the 60's that comes in handy for a variety of things, in fact it was what used to be billed as the H. Morgan Smith Worldwide Survival Tool. Good for a variety of things, great at none. You will have to decide first what you want to use a machete for, then decide what style/length will work best for you...
