MManalangMore of a family resemblance. They’re both unembellished Persian flippers with ball bearing pivots. If you stick to that basic design, you can only make cosmetic distinctions. There are anatomical differences, like frame vs liner lock, and blade steel choice, but they don’t change the appearance much, especially from the show side of the knife.
I wouldn’t knock the Gobi as a ripoff. It’s a well made budget knife for someone who wants a Persian “user” blade. Or like myself, someone who never had a Persian before and wanted to try one out without risking the week’s grocery budget. Turns out I kinda’ like it, and it’s a plus that CJRB makes pretty darn good knives at a bargain price point.
