Affut'Cap 25 cm Sharpening Stone – Corundum, Oval Section, Coarse Grit

In the field, in the vegetable garden or in the kitchen, a dull knife slows you down and tires the hand. The Affut'Cap stone is designed to fix that in a few strokes — no water, no oil, no preparation. Hold it like a sharpening steel, run the blade down the stone, and the edge comes back immediately.

The oval cross-section is the key to its success: it sits naturally in the palm of the hand, keeping fingers safely away from the blade during sharpening. At 25 cm long, it handles large butcher's knives as easily as small harvest knives, while still being easy to carry in a jacket or apron pocket. The coarse grit is calibrated to quickly recover a dull edge — this is a restoration stone, not a finishing stone.

Made in France by the Affut'Cap brand, this reconstituted corundum stone has consistent grit along its full length, ensuring even and reliable sharpening. It requires no maintenance, no soaking, no product. It is ready to use straight out of the bag.

FAQ

Can the Affut'Cap stone sharpen all types of knives?

Yes. The Affut'Cap stone is universal: it sharpens kitchen knives (chef's, fillet, paring), harvesting knives, pocket knives, garden scissors and cutting tools. Its coarse grit is best suited to blades that are truly dull. For a very fine edge on a high-end kitchen knife, a finer-grit finishing stone would be the better choice as a second step.

Does the Affut'Cap stone need to be wet before use?

No. The Affut'Cap stone is used dry only. This is one of its main advantages: no preparation, no soaking time, no oil to apply. Take it out, sharpen, put it away. Particularly practical in the field or during harvesting.

What is the difference between the Affut'Cap stone and a classic dual-grit whetstone?

A dual-grit stone (such as the Felco 902) offers two grits — medium and fine — for a two-stage sharpening process. The Affut'Cap stone offers a single coarse grit in an oval section designed to be hand-held like a steel. It is made for quick, mobile use with no bench, no water. The two tools are complementary: the Affut'Cap for fast field sharpening, a dual-grit stone for careful bench sharpening.

Can the Affut'Cap stone sharpen pruning shear blades?

Yes, with some care. To sharpen a pruning shear blade with the Affut'Cap, remove or open the shear, hold the blade flat and draw the stone along the bevel. For more precise pruner sharpening, the Felco 902 (dual-grit corundum) or Felco 903 (diamond) remain the references, as they allow better angle control.
