That depends how close the bevel is to being set and how much water is on the hone. For the other observation either you need to go further to get the toe and heel to rest on the hone or you may have a warped blade which will require a rocking motion during the stroke. Check your blade for a warp by using a black magic marker and color the bevel then go a few strokes on the stone and see where there is contact and where there isnt. If the blade is warped the toe and heel will be sharp on one side with a dull middle, the opposite will be true on the other side. If you dont have a warped blade you simply need to do more where you are at.
