Product description

The double-sided diamond sharpener behaves like a regular sharpening stone, but achieves results faster. This diamond sharpener has a fine and coarse side of 600 and 300 grit (30 or 60 micron diamonds), that is suitable for end sharpening. Doesn't need to be soaked; a light splash of water is all that is needed while sharpening.

Premium Roselli knife in dark wooden  gift box

Quality not Quantity

Each Roselli is created with the highest attention to detail and an absolute focus on quality. No shortcuts are taken – we make everything by hand, from fantastic local natural materials, using old blacksmithing techniques, in a local workshop in Harmoinen Finland. Here, everything is manufactured in much smaller quantities, which ensures that we can minimize our waste and footprint on the environment.

Premium Materials

Our products are made from the finest natural materials and raw materials that follow the highest ethical standards. High-quality carbon steel, Finnish curly birch and Finnish natural tanned leather form the basis of all our products. Our locally produced, organic and ethical leather comes from free animals and has been vegetable tanned where only organic material is used instead of destructive chemicals.
