Fällkniven DC4 Diamond and Ceramic Whetstone Sharpener

The Fällkniven DC4 is a premium whetstone combining diamond (25 micron) and ceramic (5 micron) surfaces to cover all your sharpening needs. This dual-surface design allows you to restore dull blades with the diamond side and achieve razor-sharp precision with the ceramic side. Unlike conventional stones, the DC4 remains flat over time and requires no oil or water, making it exceptionally easy to use and maintain. A leather pouch, which also doubles as a strop, is included.

The DC4 sharpener will handle all your sharpening needs. The DC4 whetstone consist of a fine diamond stone and a very special ceramic stone, made of synthetic sapphires. The advantage of these materials, although they get worn, will still keep their flat shape this is important when you sharpen your knife. And, since these materials are the hardest we know of, they will sharpen any steel, even these extremely hard powder steels. You don’t need any lubrication for these stone but now and then you should consider cleaning them with warm water and liquid soap. The stones might feel coarse from the start but will become smoother/better after some use. A leather pouch is included. The DC4 is also perfect for sharpening ice skates.

Applications

• Suitable for all steels, including extremely hard powder steels.
• Perfect for kitchen knives, outdoor knives, chisels, axes and even ice skates.
• Portable and lightweight design makes it ideal for EDC, bushcraft, camping, and professional kitchens.

How to Use

1. If your knife is dull, start with the diamond side to restore the edge.
2. Lightly de-burr with the ceramic side to achieve razor sharpness.
3. Lay the blade flat on the stone, raise the spine slightly (approx. blade thickness), and sharpen in circular motions.

Sharpening Tips

• The Ink Trick: Colour the blade edge with a felt-tip pen. Check sharpening progress by observing where the ink is removed.
• Sharpness Test: Lightly pull the edge across your fingernail. If it bites, it’s sharp enough for most tasks.
• Break-in Period: The stone feels coarse at first but smooths and improves with use.
• Leather Pouch: The included leather case doubles as a strop when used with Fällkniven’s green honing compound.
