How much typo traffic & revenue are you receiving? For me on my keyboard, the "g" & letter "k" are not next to each other so don't see how this is a typo, it's got another 2 letters in between.
It can either be a typo or K can stand for a niche K can mean Karat = Hongkong Karat But of course it is mostly like a typo because if youre using it for business, the letter K shouldnt be an initial but a whole world Im seeing this domain can sold to chinese wholesalers, stores or chinese electronic/gadget related niche I say low $xxx for now
