Added pics and specs to CS-97DEM Cold Steel Double Edge Machete
Versatile. That, period, paragraph, is the only word to describe this machete. Perhaps you might keep one edge thin for the light vegetation and the other a little on the thicker side for the heavier stuff. Or keep both edges equally sharp so that when one edge gets dull after heavy use, you can flip it over and keep on going. Two edges beats one every time!
