You want a cheaper knife than that £20 piece of crap!!! Really??
If you buy a tactical, stabby, faux fighting knife like that and expect it to actually perform as a bushcraft type knife then you really haven't a clue.
And to openly admit you made the wrong choice and fancy a refund so you can buy something else is almost fraudulent. Heinnie Haynes isn't a library or book exchange. You should learn your lesson right here, in public, embrace the suck and get yourself a decent working knife, not that mall ninja tinpot rubbish.
