I got a cheap blade off ebay and was trying to put an edge on it last night. It's a Genco B5, full ground, I think. I bought this blade to learn restoration and honing.

Anyway, I started out on a Norton 4000 and wasn't making much headway. The blade was as sharp as a butter knife when I started. I then switched to the 1000. During the process I noticed one side of the blade, the side I push away from me, the grind line was heaviest in the middle and lighter at the toe and heel. On the opposite side of the blade the grind line was light in the middle and heavier at the toe and heel. I tried to compensate by putting my finger over the spot that was light as I pulled toward me and at the toe and heel as I pushed away. Anyway, my attempt at compensation didn't work. I started out trying my best to keep the blade flat and use even pressure. I did manage to get the blade sharp enough to shave with it last night, but it certainly wasn't optimal.

Is it possible that the blade is bowed a bit? Or do you think it's my honeing that caused this? How do I correct this?
Thanks,
Kent
