Flooring or match profiles ("tongue & groove" joints) are best made
as a "stack" of cutters; or as MTP (milled to pattern) bits.
The stack heads can be resharpened, or inserts indexed individually.
Then the stack can be reassembled back on size.  MTP bits are
sharpened face only, so the profile does not change as long as the 
correct face angle is maintained when re-sharpening.
