Heres what I can tell you about it;
My friend has been using hs for 3 years now for the same annual sort of work, which is clearing his property, the same property we go to shoot! He hacks the poison oak and saplings. It does flex but is solid in the handle. It says Gerber, but its also the made in China Gerber... So for less than $20, its a decent purchase I think. The only thing he has had to do with his is to sharpen it occasionally and sharpens old school by hand, starts with a file if needed, then a stone and polishes the edge.
Now for my $20 purchase about a year and a half ago. I got this at a flea market in Jersey. It too is made in China. I looked at a bunch of machetes that day, most were of the almost non functional variety, the kind with spiked handles and cheap steel blades that arent full tang... This one was mixed in the pile. Its full tang blade has a solid wood grip which is riveted through. It is 440 stainless and is good solid blade, its quite wide and doesnt flex much at all, quite thicker than the Gerber pictured. The wood was a lighter color, so I sanded and stained it then finished with oil and wrapped the leather around it. It was a little slender for me personally but adding the leather took care of that! The sheath is a generic thin cordura thing, though I may yet one day make a leather sheath for it... just hasnt been important yet. I use it regularly on my property for clearing brush my weed eater cant handle and for holding the woods back! The woods tend to wanna sneak up on my yard!
