Anybody want to see how my rusty old brain works? This is related to my last post. If you can make out what I'm thinking here, welcome to the ranks of the old and demented school (those of us who learned to think with a pencil) 
PCustoms: Mostly, for when the one you have is "too thick" on the end but otherwise the "perfect" size for a specific job. It's always been difficult for me to get the angles even on both sides so that the resulting bit is not the same thickness side to side and thus not of the ideal geometry. Also, for when a favorite driver is borrowed and misused and you want to restore it. I know, the second problem could be remedied by just buying another tool but the first issue can only be solved by grinding it yourself.
