To keep a sportsman’s arsenal of cutting tools sharp as new, Spyderco has offered the Tri-Angle Sharpmaker for over 20 years. The updated 204MF adds a 30-degree sharpening angle for thinner blades; two other settings handle most other knives and scissors. Both medium- and fine-grit ceramic stones are included. The new Sharpmaker’s widened base holds it in place while brass safety rods keep your fingers intact, and a plastic case makes it easy to carry, although the package is heavy for field use. About $65
