Ive had 3 CS Heavy Machetes. It appears that the machete sticker is the only label CS has put on any tool now that is damn nigh irremovable w/ regular expected usage!
The markings on the CSNB and CSGK will disappear if a moth has a gastric disturbance in the general area, and those knives are $350 and less!
That being said, I HAD to sharpen all of them, after all, its a machete. Grind lines?? Well, the Gladius isnt a CS Magnum Tanto 9. Paint? It wears off, falls off...I paint the thing before I store it, grease the edge w/ Vaseline...next?? Durability??
Well, now that is a different matter entirely. I cut up TREES, couches, end tables, yard waste, cut the heads off turtles for soup and the list goes on. Did they warp a little...Yeah sure! I laid them out flat on my deck at home and hammered them straight w/ a ball peen or 3lb. steel mallet (sledge)...go again. Gave 1 to my brother. His complaint?? "The thing's too damn sharp!!" One was laid down too close to a campfire I built. The handle never melted.
Well...can't please everybody.
Im not saying you should forget it and simply buy another, but youve already spent more than the cost of a new one sweating it. So, maybe I would try again...I just wouldn't BUY it from the same place. Or anything else for that matter!
Good Luck.
