Unedged timber refers to lumber that has not been trimmed or edged after being sawn from the tree. This means that the board has irregular edges and may have some bark or rough areas still attached.

Unedged timber is typically less expensive than edged or planed lumber because it requires less processing. However, it may require more work to prepare for use in construction or woodworking projects.

Unedged timber is often used in rough construction, such as for framing or for creating temporary structures. It may also be used for rustic furniture, decorative accents, or as a base for woodturning projects.

It's worth noting that unedged timber may have more knots, cracks, or other defects than edged or planed lumber, so it's important to inspect each board carefully before use. Additionally, the irregular edges can make it more difficult to join boards together or to create clean, straight cuts.
