Whetstone, DC4 - Fällkniven
Whetstone "DC4" by Fällkniven
Length x width: 100 x 32 mm
Gross weight: 91 g
The DC4 sharpener is a newly developed combination whetstone, where one side (the bright one) is a fine diamond whetstone (25 micron), and the other (the dark one) is a fine ceramic whetstone. A leather case is included. The yellow surface consists of titanium aluminum nitride (TAN) which considerably prolongs the functional life of the whetstone. We recommend a combination of diamond and ceramic, where the diamond whetstone restores the wedge form of the blade edge and the ceramic whetstone smoothes the edge to obtain long-term sharpness. Most of the time the sharpness provided by the diamond whetstone is more than enough.
How to use your DC whetstone
If your knife is dull, we advise you to start with the diamond stone. After restoring the edge to original shape, de-burr the edge lightly with the ceramic stone in order to get a razor-sharp edge. Use no oil or water. Start by laying the blade flat on the stone, raise the blade spine approx. the thickness of the blade, and start moving the knife in circular motions.
The ink trick
Colour the edge with a felt-tip pen. You can check your progress in sharpening the knife by observing where the colour is removed.
How to check the sharpness
To check the sharpness of your knife, pull the edge very lighly on your finger nail. If it cuts, the knife is certainly sharp enough for most tasks.
Upon delivery, your new DC whetstone will appear very coarse. This coarseness will disappear when the tool is put to use.
