I call this the Skippy Oak boomerang because it has kinked wings like the Janetzki Brothers' Skippy, and because one specimen I have made of wood consists of oak scraps.

Should fly a nice midrange circle. Throw rather low and with a bit of layover. As always, if it flies too low, bend the wings slightly upwards (positive dihedral).

Make sure the boomerang lays flat on a table. Sometimes the wings will want to warp downwards. This needs to be corrected by gently bending it back, possibly applying some heat.
