Abstract: A saw comprises a generally planar saw blade, a handle, and a depth control guide. The blade has an arcuate cutting edge. A shank portion of the saw blade is pivotally connected to the handle in a manner to permit pivoting movement of the saw blade relative to the handle in a plane of the saw blade. The depth control guide comprises an arcuate depth control surface, which is adapted for engagement with a surface of material being cut with the saw in a manner to control cutting depth. The arcuate depth control surface has a curvature that approximates a curvature of the arcuate cutting edge of the saw blade. The depth control guide is adjustably connected to the saw blade in a manner so that the distance between the arcuate depth control surface and the arcuate cutting edge of the blade can be selectively adjusted to achieve a desired cutting depth.
