If you want a perfect match call the service desk at an established
lumber yard (NOT a "big-box" like HD) and ask for the name of the
nearest "custom millwork" shop. (If you happen to live in Chicago, I
use Skokie Millwork, 847-673-7868)
If they give you the name of a "custom cabinet" shop instead, that
shop will likely know who does millwork
When you find them, hanging on their wall will be *hundreds* - perhaps
thousands - of custom shaper knives they have made over the years,
likely one will be very close to your profile.
They will charge your a setup fee, maybe an minumum job fee, and
materials, and run a few feet if you need it or ten-thousand feet if
you want it - and if you want to pay a additional fee, they will
custom grind a knife from a sample of your molding.
