Frequently Asked Questions

What is the 100 grit sharpening surface used for?

The extra coarse 100 grit side quickly removes material from the blade. It is suitable for restoring very dull or slightly damaged edges and for forming the initial shape of the blade.

What is the 240 grit side suitable for?

The 240 grit side removes material less aggressively. It can be used for sharpening moderately dull knives or for smoothing the edge after using the 100 grit side.

Does 240 grit provide a final fine edge?

240 grit smooths out the marks from coarse sharpening but does not give as fine a finish as a 1000 grit or finer stone. For a very smooth and refined edge, continue sharpening with a finer stone.

How to use Smith’s Dual Grit sharpening stone?

Apply a little suitable sharpening oil to the stone, place the blade on the stone at about a 20° angle, and move it across the surface with moderate pressure. Treat both sides of the blade equally and keep the sharpening angle as consistent as possible throughout the movement.

When is Smith’s 4" Dual Grit the right choice?

This compact sharpening stone is best suited when the knife has become very dull or the edge needs quick restoration. The 100 and 240 grit surfaces remove material relatively aggressively and help restore the blade shape faster than a fine finishing stone.

If your knife only needs light maintenance sharpening or you want a very smooth edge, choose a 400/1000 grit combination stone or a natural Arkansas finishing stone. For regular sharpening of longer kitchen knives, a larger bench stone may be more convenient, but the 4-inch model’s advantage is its portability.

Expert recommendation

Smith’s 4" Dual Grit is primarily a tool for blade restoration, not for final fine finishing. Use the 100 grit side only if the edge is very dull, uneven, or has minor damage. If the blade only needs refreshing, start with the 240 grit side, as this removes less material and extends the knife’s lifespan.

Apply a small amount of suitable sharpening oil to the stone and keep the blade at as consistent an angle as possible throughout the movement. The recommended angle in the product description is approximately 20°, but the exact choice depends on the knife’s construction and the manufacturer’s instructions. Treat both sides of the blade equally and avoid excessive pressure.

After use, clean the stone with soap and a brush, rinse under running water, and allow it to dry completely. Store the dry stone in the included pouch in a place where it cannot fall or be subject to impacts.

Compact double-sided stone for blade restoration

Smith’s 4" Dual Grit combines a 100 grit restorative sharpening surface and a 240 grit smoothing side in one pocket-sized stone. It is a practical choice for hunters, hikers, or knife owners who need a portable tool for quickly restoring dull edges.
