Yeah , Canku is a company you'll find that a lot of collectors avoid . Canku steps pretty heavily into cloning. You'll find Marfione, Rockstead, Shirogorov , and even Bastinelli clones on the first page of an Amazon search. They even dabble in the lower end with a Kershaw Cinder clone (advertising better materials than Kershaw at an unusual higher price). I can see the temptation, doubtful that I'll ever be able to afford some of the true name brands myself ( some ranging from $800-$2000, offered for $20-$40). At the end of the day I've always felt your money your choice, and with Amazon offering them so freely it's hard to condemn and be taken serious. It's just something I think you should keep in mind, and if you were unaware it's just to inform.
