Frequently Asked Questions

What are the 400 and 1000 grit surfaces used for?

The 400 grit side is for restoring and primary sharpening of dull edges. The 1000 grit side is then used to refine the blade, improve sharpness, and achieve a smoother edge.

Is the Smith’s 400/1000 sharpening stone suitable for beginners?

Yes, but freehand sharpening requires maintaining a consistent angle. Beginners should work slowly, use light pressure, and practice first with a less valuable knife.

Is the sharpening stone suitable for serrated blades?

A flat sharpening stone is primarily intended for straight-edged knives. For maintaining the individual recesses of a serrated blade, use a cone or rod sharpener of suitable diameter.

Should the sharpening stone be used with water or oil?

Follow the instructions on the product packaging or included manual. If no specific lubricant is indicated, consult the seller before use and do not switch between oil and water on your own, as the substance absorbed into the porous stone will affect its future use.

Does 400 grit remove deep chips?

400 grit is suitable for restoring normally dulled blades, but for deep chips, broken tips, or major re-profiling, a coarser abrasive or professional sharpening may be needed.

When is Smith’s 400/1000 sharpening stone the right choice?

This double-sided synthetic sharpening stone is a good choice for users who want to perform both primary sharpening and fine edge finishing with one compact tool. Manual sharpening allows you to choose the angle best suited to the knife’s geometry and remove material more precisely than with a fixed-angle pull-through sharpener.

For heavily damaged blades or extensive re-profiling, it may be wise to start with a coarser stone. For quick processing of especially hard steel, consider a diamond sharpening stone. If easy and fast sharpening without manually holding the angle is most important, a fixed-angle hand sharpener may be more suitable.

Expert tip

Start sharpening on the 400 grit side only if the knife is noticeably dull or the edge needs restoration. Keep the blade at as consistent an angle as possible throughout the movement, and use moderate, even pressure. Excessive force does not necessarily speed up the process and can make the bevel uneven and wear the stone faster.

Once a slight burr has formed along the entire edge, move on to the 1000 grit surface. Gradually reduce pressure and alternate sides regularly. This will remove the sharpening marks left by the coarser side and produce a cleaner edge.

Always place the base on a stable, non-slip work surface and move the blade away from your body and fingers. After use, clean the stone according to care instructions, let it dry completely, and only then place the protective cover on the dry stone. This helps prevent dirt buildup and maintains the performance of the sharpening surface.

Practical sharpening stone with two grits

Smith’s 400/1000 combines a medium surface suitable for restoring dull blades and a fine edge for finishing, all in a single 15 cm stone. The base with a protective cover makes this a practical choice for regular knife maintenance at home or for taking sharpening equipment on the go.
