I have to say I completely agree on the fitness of this knife, it sucks!! You are being too kind in even calling this thing a knife, more like a boat anchor. I have never handled anything more useless!
I went to a Bushcraft, week long course last year and one of the students had one of these along with a custom ($300) sheath. He was determined to use it for all the tasks and to his credit he managed. He just worked 10 times harder than anyone else to make a spoon, bowl, notch trap sticks and make bow drill sets. The director of the course brought out his combo waterstone soaked in a container of water and showed us how to sharpen and left it out for us to touch up our blades. I watched this poor guy try to actually sharpen this hunk of scrapmetal. Myself, I can sharpen a knife, been a passion since I was a Boy Scout decades ago. I tried to sharpen it for him with no results, it simply could not take an edge with the tools at hand. Metal seemed way too hard. He made it through the course and was persistant. I guess if I paid $700 for a crap knife and sheath, I'd be determined too.
Bottom line, it should be returned to the maker for a refund, unless you need a boat anchor. Cheers!
