This triple input sharpener from Möbius and Ruppert (or M+R) cuts wood on standard diameter pencils, points, and leads. Wood pencils can be sharpened in three different ways-: standard sharpening, removing wood without sharpening the lead, and point the lead only. 
 
M+R, has a history within the pencil industry that dates back to 1908. They have produced high-quality sharpeners since 1922 and now offer a range of other tools.
