Precise adjustments for leveling knives • Simple to use Why pay $133 for an amana mks-100?  This jig is manufactered in the same plant in China, its the same tool.  All we can tell is Amana's  wooden box is sprayed with a clearcoat, where as ours is ready to finish.  Same jig as CGG Schmidt.  In essence, we are all selling the same imported jig..
