Eased Edge
A slight rounding applied to the sharp corners of a board during milling to reduce splintering and make the lumber safer to handle.
In-Depth Explanation
Eased edges are a small but important detail in modern lumber production, created by running boards past rounding cutters at the mill after surfacing. The resulting radius is typically 1/16 to 1/8 inch, just enough to eliminate the sharp arris that would catch on skin and gloves. Building codes do not require eased edges, but nearly all major softwood mills apply them as standard practice for safety and to reduce shipping damage. For finish carpentry where crisp edges are desired, eased edges can be removed with a jointer pass. When a more pronounced rounded profile is desired for deck boards or handrails, a router with a small round-over bit can enhance the factory profile.
Usage Example
The 2x4 studs from the home center all had eased edges, which made them comfortable to handle without gloves during framing.
