Do you have a Boston 18 or 19 Pencil Sharpener in need of a gear?? Look no further! 

My gear doesn't need crazy filing or tweaking it just snaps on! How is that possible? Easy, I test fit every part in my Boston 18 so you don't have too! 

This gear will NOT work in a Boston 17. How can you tell the difference? Easy the 18/19 use a white plastic gear to drive the large gear. The 17 uses a metal gear. Look in my photos -- if your gear doesn't look like mine -- let me know and I will send the appropriate gear.
