FAQ: What are the advantages and disadvantages of a convex grind?

What it is: On a convex grind, the sharp edge is produced by symmetric, gently curved surfaces. Where the curvature begins (high or low on the blade) can produce a full convex, a saber convex or even a Scandi convex grind. Many knife aficionados consider a convex grind the strongest and most durable profile.

What it's good for: Hunting, woodworking, food preparation, axes, general use.

How to sharpen it: Sharpening a convex grind requires an abrasive surface that ever-so-slightly "gives" to follow the curvature of the blade -- generally, a leather strop or hone (a piece of leather affixed to wood base, with abrasion provided by stropping compound or sandpaper).

What you may not know: A practiced hand can sharpen a convex-ground knife on a hard surface or a flat stone. Because it's relatively difficult to master, however, this technique is best reserved for emergencies in the field.
