Thanks guys. Not sure what I'm going to do. I have a huge nick in the blade and I really don't have the tools to fix it.
Do you think blade replacement costs would be about the same as purchasing the equipment needed to fix it? I don't remember how much they were now, but a while back I purchased the SharpMaker Diamond Rods to fix a blade that was messed up beyond what the medium stones could really manage. I figured just buying the rods would take care of it then and if it ever happened again. I now use an EP, but was able to fix some pretty bad chips on a S30 knife with the SM diamonds. My only complaint was that they wear fast, so I only used them for heavy work that would wear the medium rods to a point making the more aggressive cutting diamonds a more economical and practical option. They cut aggressively on even higher wear steels like S30, so I imagine they would cut even more aggressively on 440.
Even with the larger chips, I've been most successful sharpening on the same angles/same pressure as if there was not a chip, but just extending the duration of sharpening longer until the chip itself has been sharpened out. I'm not sure how many methods there are to it, but that's been successful for me personally. Not sure what size the damage you're dealing with tho...I imagine if the chip is too large that my method would simply remove too much metal
