Maybe there is a better and different way to do this base cabinet, but here goes. A spice'n'oils pullout is to be built, cabinet is frameless, and the front is a maple slab, 6-7/8" w x 30-1/8" h, with a 1/8" x 1/2" d kerf cut into it to emulate the drawer-door margin of the adjacent cabinet.
All the fronts have their edges eased with a 1/16" R roundover. How would you round the edges of the kerf?
