Thanks for the feedback, Aedalas. The snips cut through the knives like butter. If done carefully then it won't deform the metal, however I have tested the metal and have found it to be very strong. If it was deformed during the process it could probably be reshaped without compromising the metal's strength. The snips I use are just the regular, yellow handled ones:
I do quench the metal while grinding, it's one of the most important yet overlooked parts of the process.
As far as the diamonds go, I got the idea for the curve from Wizwazzle on youtube. I've found it to be more useful for raking than SPP but I've used it for both. The bottom one is a funny story actually. I modeled after the first pick I ever made, which could open every master lock I tried it on in just one rake.
The wider shank was just the way I made it, I suppose my interpretation of the half diamond was a little off. Strangely enough the wider shank seems to greatly improve the effectiveness of the pick when raking.
