For something around a pound that chops well and is highly affordable, might I suggest the Kabar Heavy Bowie, ZK War Sword, or their Camp Machete? I own a Heavy Bowie, and I think it would be very difficult to beat in it's price range. As 42 knows, I'm also waiting for my money situation and his stock situation to match up for a Condor Thai Enep.
Not sure where you're at money-wise but I should have some Eneps in both sizes arriving tomorrow.

The Kabar Heavy Bowie is an excellent value--I just happen to disagree with its design configuration. Too thick and stubby for me--I like longer, thinner, and broader for equal mass due to the additional mechanical advantages it brings. It sure seems to be a crowd pleaser, though, so if it's appealing to you you sure can't go wrong! I consider the Kabar pieces chopping knives rather than machetes, contrary to the company's self-classification.

The new Grass Machete is properly identified as a machete, in my opinion, but I wouldn't use that one to cut grass! It's a bit short and thick for that--actual grass machetes (like the "sable" pattern) are more like 20"+ long sharpened steel feathers. You need reach and tip velocity for grasses.
If I were to pick one of the Zombie Knives series for a chopper, though, it wouldn't be the War Sword. I'd go with the Pestilence Chopper. Same general profile as WWII machetes Case put out, folding and fixed. :thumbup:
How about the ESEE lite machete? I read somewhere it basically has the same blade as the eco.
Also, what about the Condor El Salvador 14"? I just saw it's a 1/8" machete.
Sorry for these short retarded posts
The ESEE Lite Machete is an excellent piece of work, and the only micarta-handled machete on the market without an exposed tang that I know of. The blades are, indeed, identical to the EcoSurvivor, and are supplied by Imacasa/Condor to ESEE. They then laser-cut the tangs to exact spec so the machined micarta scales can be attached securely and without any wobble. I do find that the factory sheath leaves a lot to be desired, so I suggest getting the sheath to an 18" El Salvador machete for it if you go that route.
The 14" El Salvador is a chopping machine and I love the profile of the blade. Looks just like an old Collins. Wish I could get them back in stock, though. You might find someone else who has them kicking around though.
