designed by bryan wong and chengtao yi, the ‘zirconia sharpener’ is a reinterpretation of the traditional pencil sharpener that offers a smooth sharpening experience. made from zirconia and fused into a single unibody block, this sharpener enjoys the characteristics of a material that, unlike other ceramics, has a high resistance to crack propagation, as well as high thermal expansion. by utilizing zirconia’s properties, the blade doesn’t need to be changed, creating a lifelong companion for those who use pencils.


‘for drawing and note taking, we always sharpen our pencils. we believe a pencil sharpener made with a beautiful and durable material is functional hence leads to desirability. we love the beauty of simplicity, and the magic of analog. it’s honest and thoughtful,’ comment the designers on the sharpener.
