Smith’s Pocket Pal Knife Sharpener

Want a quick, foolproof way to hone your blade in the field? This pack-of-gum size tool makes it easy. Two V-shaped guides give you a perfect grind every time. Use the carbide slot first to set the edge, then pass it through the ceramic side to fine-tune. A rod even lets you sharpen a serrated blade. “I brought my old knife back to life in three minutes,” says one tester. $10; 1.5 oz.; smithproducts.com
