Heljestrand and Boker are excellent brands. The Hele looks real good and so does the Dorner.The Larsen is a bit rough and the Boker is worn but for starting out with learning to hone they are fine since you got them cheap.

FWIW, I take something like that Larsen and I don't worry about the rust beyond polishing with Flitz or Maas. I hone the chip out and go from there. You have some potentially good shavers there.

If you haven't done so check out the basic honing forum and the videos. Lots of good stuff in newbies corner too. Best of luck with your razors.
