Toyama Hamono R2 Slim Shear Sharpening Stone, #320

A slim #320 whetstone that sharpens pruning shears without taking them apart.

Dull shears crush stems instead of cutting them. The R2 is a slim whetstone made by Toyama Hamono to sharpen pruning shears without disassembling them: its thin profile reaches the narrow gap near the pivot. It works on all types of shears and cutting tools, and on other blades too. The grit is medium, #320.

Why we carry it

We’ve been curating design-led pieces since 2009, and we look for tools that earn a place in the house as well as the garden. Toyama Hamono was founded in 1861 in Sanjo, Niigata, a city with a long tradition of metalworking, and still forges its shears by the traditional tanzo method. Its work has been recognized with the Good Design Award and as Sustainable Garden Product of the Show at the 2023 Melbourne International Flower & Garden Show.
