The word "compass plane" refers to a type of hand plane that is used to create circular or rounded surfaces. While there are no direct synonyms for this specific type of plane, there are several tools that can be used for similar purposes. These include the spokeshave, which is a handheld tool used for rounding and shaping wood; the drawknife, which is used for removing larger amounts of material from a surface; and the gouge, which is a chisel-like tool with a curved blade used for carving and shaping. While each of these tools has its own specific uses, they can all be used in conjunction with a compass or straightedge to create curved or rounded surfaces.
