Naniwa Whetstone #400 Pocket Pro Stone 13.5x4.5x1.5 cm PS-304

The Naniwa Pocket Pro Stone 400 grit is a compact yet extremely powerful sharpening stone, designed for fast steel removal and effective edge restoration. Ideal for dull or damaged knives, this coarse grit stone makes quick work of repairs, bevel setting, and heavy sharpening tasks. Its small size makes it perfect for outdoor use, whether you are camping, hunting, or maintaining tools on the go.

Despite its pocket friendly dimensions, this stone delivers the same high performance as the full size Naniwa Professional series. The hard magnesia bonded structure ensures excellent feedback, minimal wear, and long lasting flatness, even under demanding use. It is especially effective on rugged outdoor knives, pocket knives, axes, and other tools where handheld sharpening is required.

The splash and go design means no soaking is needed. Simply wet the surface and start sharpening immediately. After restoring the edge with the 400 grit, following up with a finer stone is recommended for a refined and razor sharp finish.

Manufactured in Japan by Naniwa, this pocket stone represents the highest quality in sharpening technology, now available in a highly portable format.
