In my opinion this is simply the world’s greatest machete. If you don’t already own one, you MUST. It will make easy work even of removing blackberries and anything else up to 1″ or more:
487 grams on my scales
I have the Gerber version (http://www.amazon.com/Gerber-31-000083-Gator-Brush-Trimmer/dp/B0025VKMI2) 429 grams which is probably much the same except it comes with a handy Cordura sheath instead of the plastic arrangement the Fiskars has.
