HAIDU CERAMIC

Haidu Ceramic began developing products over 15 years ago, first introducing a silicon carbide-based grey whetstone. In 2019, the material was changed to aluminum oxide, giving the stones their current light shade.

All Haidu stones are entirely handmade.

We offer two different sizes:

• HVA – full-size stone
• HCZ – smaller stone with rounded edge

The smaller stone is excellent for sharpening knives, utility knives, axes, and other tools. The larger stone, on the other hand, is cost-effective, hard, and durable – ideal for sharpening knives, chisels, and plane blades.

From my own experience, the larger 250-grit stone has proven especially effective for rough work and knife repair. Even major damage, such as broken tips, can be reshaped entirely with this hand stone – no need for power tools. The hardness of Haidu stones plays a crucial role here, as many coarse stones tend to be much softer. With Haidu, you can work with considerable force without the stone wearing down excessively. Of course, heavy pressure will still leave some marks, but compared to many other coarse stones, Haidu clearly stands out for its hardness.

I first became fond of the 600- and 250-grit stones, and only later started using the 1000- and 3000-grit versions. These finer stones opened up a whole new world: they provide a unique, pleasant sharpening feel – and I mean that in the best sense.

The latest test demonstrates how Haidu performs in chisel sharpening.
