blond hash is hash made just by pressing kief, in order to get a blacker hash i have found it a necessity to add alcohol then after pressing (i do this by hand haven't tried it with kief press) let the alcohol evaporate. it comes out as like a play-doughish substance which is quite sticky with is perfect for bt's as the hash doesn't ever fall off the cig.
EDIT: i used to own a metal grinder with a kief catcher just like yours and buying an electric grinder and a sifter makes 2-3x the crystal you would normally get.
