KnitKing is just another brand name for Japanese knitting machines manufactured by Brother Co. Yet some of the KnitKing machines (mostly older) are rebranded Knittax models.
Below is the list of models I’ve seen branded as KnitKing. If you do not see a machine model number you are interested in, check out the Brother Knitting Machines page, as the model numbers are often interchangeable.
