To find the center, insert work piece into the 'V' of the square and mark a line.
For round stock, rotate the piece 90 degrees and mark again. The intersection of the lines is true center.

Nicholas ★★★★★

I was a little skeptical at first, but placing a rod in the V-groove and rotating it 90 degrees gave me a perfect intersection every time. The 3-inch square handled a thicker shaft nicely, and the scriber made a precise mark without slipping.

Ruby W. ★★★★★

Used it on some round stock this weekend and the double-line method hit center dead on both 1 1/2" and 3" pieces. The V-groove holds the work snug enough that my scribe lines didn't wander. Solid little set for the money.

Benjamin ★★★★★

The 90-degree trick with the V-groove is dead simple—I chucked a dowel in, scribed two lines, and hit center on the first try. The 3" size handles bigger stock without wobble, and the scriber tip feels sturdy enough for daily use.
