Compare documented historical and newly made hand-cut dovetails with machine-cut examples. Spacing, layout lines, and saw cuts are observations, not a date.
Historical hand-cut, newly made hand-cut, machine-cut, and factory-made dovetails. Labels mark spacing, layout lines, and saw cuts.
Look at spacing, layout lines, and saw cuts
Hand-cut dovetails often show uneven spacing, a scribe or layout line, and saw cuts that stop short of a perfect machine edge. Machine-cut and factory-made dovetails tend toward even spacing and uniform tails. Those are descriptions of how the joint was cut.
A new hand-cut joint can look irregular
The newly made hand-cut example in this gallery also has slightly irregular spacing and visible saw marks. Irregularity records a hand process. It does not, by itself, assign a century. Use the comparison to describe what you see, then keep dating to marks, hardware, materials, and documented history.
