Rockler Woodworking and Hardware has a new tool to mark the center on a board's edge as well as scribe precise lines for rabbets or reveals along the board's face.

The Rockler Center/Offset Marking Tool accepts a common No. 2 pencil and has two posts that straddle the board's edge. The user twists the tool to bring the posts against the board, perfectly centering the pencil, and moves the tool along the board to mark the centerline. It works on stock up to 1-1/2" thick, according to the company.

To mark for rabbets, reveals, molding offsets or mortise locations, the user simply flips the tool, presses it against the edge, places the pencil tip at the desired offset and slides the tool to make the mark. The tool has marked offsets ranging from 1/16" to 1/2" in 1/16" increments.

"Anyone who's tried using a tape measure or a combination square to mark the centerline on the edge of a board knows how awkward it can be. This tool makes it simple — and ensures absolute accuracy," Rockler vice president of merchandising and proprietary Steve Krohmer said in a statement. "And for marking offsets, it doesn't get any easier."

The Center/Offset Marking Tool sells for $9.99.
