Product Description

Fallkniven Double Diamond Folding Whetstone (FDD) 4" Double Sided Whetstone, Medium| 44 Micron, Fine| 25 Micron, Foldable

The FDD sharpener is a foldable two-sided sharpener that features diamond-coated surfaces on both sides. Its foldable handles ensure safer sharpening without the risk of cutting yourself. As knife steels continue to improve in strength and hardness, it becomes crucial to have reliable tools for processing these knives. Drawing from Fallkniven's extensive experience in outdoor settings, they believe that the diamond sharpener is the ultimate tool for standard knife sharpening. Moreover, even with wear, diamond whetstones remain flat, offering a significant advantage when it comes to long-term knife sharpening. Additionally, these whetstones are known for their fast action, allowing you to achieve a new edge with remarkable speed. The best part is that no oil or water is required during the process.

The sharpener's yellow surface is made of titanium aluminum nitride, which significantly extends its lifespan. When sharpening, use the rough side (44 microns) for repairing actual edge damage and the fine side (25 microns) for regular edge maintenance. An English instruction manual on how to use the whetstone is included. To clean it, simply use some washing-up liquid and hot water. Please note that like all diamond sharpeners, this whetstone may feel a bit rough initially but becomes smoother with continued use.
