Fantastic sharpening stones, specially designed for secateurs but also great for shears, topiary clippers and other sharp stuff.

The bottom of each stone is slightly concave and designed in such a way that it fits the convex curve of the cutting blade perfectly on all our secateurs. This makes it easy to get the angle of attack correct, ensuring great sharpening results every time.

The flat face(s) of the stone are ideal for shears and topiary clippers and for removing the burr from reverse of the blade after you have used the concave face to sharpen secateurs.

They’re small enough to get into tight spots, so you can sharpen all the way along the blade, and come highly recommended by Japanese blacksmiths and Niwaki's own master pruner, Jake Hobson.
