I am looking for a brand name for a "go-to" diamond profile parting tool, I have a couple of PSI Benjamin's Best but have a problem with them. No knock on PSI tools in general, I've had great success with them as utility tools that I regrind to my shapes. I don't use a parting tool a lot, I usually make tenons and such with the Bedan or a skew chisel, and I cut off with a skew or my thin fluted parting tool - but I'd like one good utility diamond parting tool of about 3/16" or 1/4".
The problem with my BBs is that the edges (top and bottom) are not perfectly parallel, nor perfectly aligned with the high points (sides) of the diamond. That makes sharpening a pain in the butt. I'd like to have a parting tool that I can lay flat on its top and bottom edges on my tool rest and get a grind that has the end points at the wide points of the diamond. I know how to get around it, but it would be nice ot have one I don't have to fuss with. Does anyone know a brand that is consistent in its shape?
