I've got a Dovo Best Quality for Christmas. Since then I've used it every other day with no issues other than noobie nicks. Today however when I went to shave my razor wouldn't cut the hair. I've stropped it a few times since receiving it with no issues. I put it to the strop about mid shave since it wouldn't cut at all with no positive results. The razor won't even hang up on a hair. It just glides right over everything taking the lather with it.The bottom third of it however cuts just as well as it did on day one (received it truly shave ready from straight razor designs). Any idea what could be causing this? How can I fix it? Also, I'm noticing tiny black specks about a cm from the edge which I'm assuming is rust. I dry off the blade after each use using a piece of toilet paper, then air dry it with some of the canned air stuff you use on computers. What can I do to remove these specks?
