i've been trying to sharpen one of my knives on my smith pull through, buts it taking forever. it always takes forever but this time its worser. i thought it had something to do with the black coating (maybe?) but i was told here it wasn't true. now I'm starting to think that maybe i heated the blade up too much sharpening it and when i went to wash it i cooled it too fast and hurt the temper and made it too hard. wonder if heating it in an oven would make less hard as i was told by a friend it would make metal softer, but I'm afraid it will melt the plastic handles.

any thoughts are appreciated. :thumbup:

What has happened is that over the years, the pull through has been sharpening the edge. But each time it sharpens it removes some of the metal away so to make contact between the knife edge and the sharpener, the blade sits lower and lower. At this point, the blade cannot lower itself enough because the thickness of the blade sides are rubbing against the side of the sharpener keeping it from going lower to make contact with the edge and the sharpener. You would need to make the sides of the knife thinner so that the knife can slide down and make contact between the knife edge you are trying to sharpen and the sharpener.
