I recently ordered a couple of Bearclaw Sitka guitar tops and I wanted to let you know that not only did they arrive safe and sound but they are beautiful. Amazing figure! Having been less than satisfied with some wood suppliers over the years it's comforting to know that LMII has consistently come across in both quality and integrity. I never have to worry and that's a wonderful thing!

Thanks again,
Marc Beneteau



Kerfing (L-R): Reverse, small, standard, triangular, and unkerfed. 

Our kerfing is a full 32 inches long
as opposed to the 16" long kerfing found elsewhere.


We are having trouble sourcing affordable spruce from which to produce spruce kerfing. While we continue our hunt, basswood kerfing is a good substitute.


Kerfing (or lining) provides a gluing surface for the joining of the backs, tops, and sides. Some builders use it with the kerf facing out, so the kerfs are visible, and others glue the kerfed face to the inside hiding the kerfs. Some builders choose the same type of wood as the soundboard for the kerfing along the top and sides.

5 profiles are offered in different woods:
  • The standard profile is the most traditional for steel string guitars and modern classicals.
  • The triangular profile is used if you have a smaller instrument, or binding and purfling scheme.
  • Our reverse kerfing is designed to give added stability to the sides. By gluing the kerfed face you effectively make the side that much thicker (and therefore more rigid) with little weight or mass added. With a radiused top edge, it presents a very clean look inside the body.
  • We offer unkerfed Basswood lining for more traditional classical guitars.
  • Ukulele, dulcimer and mandolin builders can use our small square kerfing.
