Examine under magnification
I have dozens of razors in my study collection and many are old and some are new. The toes and heels are especially "issue" areas even with brand new factory blades. If you watch the video of the Dovo manufacturing process, you'll see that most of the honing is on the center of the blade and not the toe or heel. In the knife industry we call that a "factory edge" and it's fine for most folks but many like to bring out the true potential of the steel and heat treat. You'll have to do your best on the toe especially as it's important for the hollows in your neck (well, my neck anyway...).
