If you are new to honing razor you sure picked a challenging combination. It is a long step from a 3K to a finisher, so in order for it to work your 3K edge needs to be absolutely perfect. The heavier the grind the more stell that needs to be removed to cut a nice perfect bevel. You should be able to get an edge that will shave from the 3K. It will be very rough, but it will shave. If you do not have any optics, stay on the 3K until you can get it to shave and then move up. You will need to be doing very light passes on the 3K before you move up. A loupe changes my honing substantially and removed all the guess work. If you don't have a budget for hones you could send this razor out.
