Can I sharpen tools other than pocket knives with this?
Yes. While it is optimized for EDC (everyday carry) and hunting knives, it is versatile enough to sharpen kitchen knives, scissors, garden shears, fishhooks, and even broadheads.
Do I need to use water or oil while sharpening?
No. Both the diamond and ceramic surfaces are designed to be used dry. This makes it much cleaner and more convenient for use in the field or while traveling.
Why are there two different angles (20° and 25°) on the guides?
The 20° guide on the diamond plate is designed for shaping and repairing a dull edge. The 25° guide on the ceramic plate is slightly steeper, which allows you to quickly hone and polish the very tip of the edge (the micro-bevel) without having to remove as much metal.
Are the sharpening plates replaceable if they wear out?
The diamond and ceramic plates are permanently adhered to the frame to ensure a slim, durable profile and are not replaceable. However, they are built from high quality materials designed to last for many years of regular use. The only user-replaceable part is the pocket clip.
Is this sharpener suitable for beginners?
Absolutely. The built-in angle guides take the guesswork out of sharpening, helping beginners maintain a consistent edge. It is an excellent tool for learning the fundamentals of manual sharpening.
How do I clean the sharpening surfaces?
Over time, metal "swarf" (tiny metal shavings) can build up on the plates. You can clean the diamond and ceramic surfaces using warm soapy water and a stiff nylon brush. For deeper cleaning of the ceramic plate, a standard pencil eraser can often "erase" the metal buildup.
How do I carry it securely?
The sharpener features a slim, folding design that protects the sharpening surfaces when not in use. It also includes an integrated pocket clip, making it easy to secure to a pocket, belt, or MOLLE webbing on a pack.
Will it work on extremely hard "super steels"?
Yes. Because the primary sharpening surface is a 400 grit diamond plate, it is capable of sharpening even the hardest modern knife steels that traditional whetstones might struggle with.
Can I use it while the tool is folded?
The tool is designed to be unfolded during use to provide a stable handle and proper access to the angle guides. When unfolded, the ergonomic grip keeps your fingers safely away from the blade’s edge.
