With the large amount of experience within SRP I am hoping that someone could guide me. I was recently attempting a dissection at the University only to find that all of our brain knives are dull, chipped and the tips are bent (not that I use the tip). I discovered that one professor allowed a class to use them without instruction.
I decided that rather than deal with a request to the department for new knives or sharpening services I will take it upon myself to sharpen them one at a time until they are all good.
While inspecting these I realized that they have a very wide spine and are hollow ground. I couldn't see a bevel at all. All I can assume is that they were sharpened on the wheel when they were ground.
I am really unsure about resharpening these. I don't know if they are meant to be sharpened with the spine rubbing like a razor or if I need to make a specific angle to accomplish the best edge. I have a wide range of hones to choose from including my razor hones (would prefer not to use them), a tormek, a range of lower grit carborundum, diamond and harder synthetics. I'm not really worried about stones, but I am curious how I should go about this mechanically or how high I should go in grit.
Any guidance would be greatly appreciated.
Thanks!
