All metal durability. Has 2 holes for sharpening standard and large pencils. Also for sharpening charcoal, pastel, and colored pencils.
Alvin makes this all-metal sharpener with 2 holes, one for standard size pencils (8 mm), and the other for large size pencils (10.5 mm). Even if you don't use large-size elementary school pencils, the larger hole is handy for careful sharpening of charcoal, pastels, and colored pencils.
