Guys, the length here doesn't matter :P
I went to buy the longest length in terms of money. But it's too heavy, man, and I'm a hardworking guy. I would recommend something around 50 centimeters if you want it long, otherwise, even in a smaller size, it's definitely more practical than the 71-er. Surely, the length will help with the power of the hits it delivers, but for trips to the mountains with my 2.5-year-old son, it's excessive. Anyway, it's worth its money, and this brand is well-known for the quality they have in their machetes
