I have been using MLCS shaper bits for making raised
panels & doors for the last several years. They have performed
fairly well considering the price.

However, my last project involved making about 24 raised
panels from MDF. This left my raised panel bit in very
dull condition. I have tried sharpening it by using a set of
diamond sharpening tools (the cheap flat ones) using 400,
600 and 1200 grits. I probably spent well over two hours
on this, but although it came out sharper than when it started,
it is nowhere near the razor sharp condition I was used to. Of
course, I didn't know exactly how to do it - just tried to follow
the original angles.

Anyhow, has anyone tried to do this or is there a professional
sharpening service that could do it or should I just figure that
I got my money's worth & buy a new one? I think I paid around
$75 for the bit.

By the way the coping set which I used only on oak & poplar
has been holding up much better.

Any help/advice would be appreciated.
