Precision Tolerances / Custom Finger Joint Cutters
Reversible
By far the most common joint.  Requires two heads; one with a thick cutter at the top of the stack and one head with a thick cutter at the bottom of the stack. This joint may also be achieved on a single head shaper by reversing alternate pieces of stock machined.

Male-Female or End Match
Less common joint than reversible. Always requires two heads; one with all thin cutters and one with a thick cutter at both top and bottom of the stack.

Re-Saw
Special joint with thick cutter at center of stack to allow for finger jointed stock to be split or re-sawn into two pieces.

Scarf Or Feather Joint
Usually requires no thick cutters. Used when dimensions of stock will vary significantly.

Half-Shoulder
Requires special length thick cutters.  Often seen in finger jointed chair backs or miter cut parts.
