Well, there isn’t one here at my house. I’ll check those on Amazon again and go medium cost, whatever that is. It needs to keep an edge and be able to take down those vines/limbs. Those limbs are not thick and woody at this time but they will get that way. I need to whack them down when cool weather gets here. It’s about 100 degrees every day right now.
You can keep that 100*, I can’t breath air that hot.
Get a standard US-military-issue machete. The 18” one works fine. There’s a longer one available too, and one with a sawblade on the spine, but I don’t know how useful either one is. My 18” army-issue has lasted 20 years, and would cut through anything up to a 3/4” branch when properly sharpened. They cost about $23 from US Cavalry: http://www.uscav.com/search.aspx?search=machete&tabid=548&os=1&catid=5230
