Diafold Double-Sided Sharpener

The DMT Diafold Double-Sided Sharpener is a classic for a reason. Its core appeal lies in its simplicity and effectiveness. You're getting two distinct diamond grit surfaces – usually a fine and coarse, or extra-fine and fine – housed in a durable plastic handle that folds over itself to protect the sharpening surfaces when not in use. This clamshell design makes it incredibly packable and keeps grit from contaminating your pack or pockets. The monocrystalline diamond abrasive, a DMT hallmark, is aggressive enough to quickly restore an edge, yet fine enough on the higher grits to achieve a respectable working sharpness on knives, tools, or even fish hooks. It excels at quickly addressing dullness and can handle a wide variety of steel types, from basic stainless to more advanced alloys, without fuss. While it might not deliver a mirror polish, it consistently provides a very keen, toothy edge suitable for field use.

Construction is straightforward: a polymer handle encasing two diamond-coated steel plates. The plates themselves are robust, designed for years of use, and unlike natural stones, they don't dish or require flattening. This means consistent performance over the long haul. At a competitive price point, it stands out for its maintenance-free nature and the speed with which it cuts. It's not a replacement for a full bench stone setup for precision honing, but for on-the-go maintenance and edge restoration, it’s remarkably efficient. Its light weight and compact size make it an easy choice to throw into any kit.

What truly sets the Diafold apart is its sheer versatility. Whether you're touching up a knife mid-hunt, putting an edge back on a shovel, or even sharpening fishhooks on the riverbank, it handles it all. The grit options cater to a range of sharpening needs, from reprofiling a damaged edge to refining an already sharp one. It's a no-nonsense tool that delivers reliable performance, making it a staple for anyone who relies on sharp edges in the field.
