Pollux Brass Concave Sharpener
This product is currently sold out.
As the rarest type of single-hole sharpener, this is one that we've been patiently anticipating the arrival of since early 2015 when it was first introduced. It's made of solid brass and has a blade that carves the pencil to a concave point that's longer than usual. It's convenient and elegant--a win-win in our book. For those on the hunt for a coveted antique A.W Faber Janus sharpener for its similarly concave capabilites, this is a comparable alternative.
Made in Germany
Single-hole, can accommodate normal diameter pencils.
*Though this sharpener sharpens beautifully, it only works perfectly on high-quality pencils with well-centered cores.
