A sharpened pocket knife is imperative for safety and control as well as for function. A dull knife blade can slip and cause an accident when more pressure is put on it in an attempt to cut. A best pocket knife sharpener is necessary to ensure your blade is always ready when you need it. Portable pocket sharpeners are convenient although electric countertop models are versatile for more types of knives than just those used outdoors. Hand sharpening using a whetstone lubricated with oil and water is the traditional method used to sharpen any outdoor knife. They are compact, lightweight, and portable. Many are dual-sided, having a coarse grit side and a fine grit side.
There are also diamond, ceramic, and carbide pocket sharpeners. Electric knife sharpeners are not portable and they are more expensive. But they sharpen your blade quickly and to a razor-like edge.
Knife sharpeners are compared according to their type (bench stone, electric, etc.), their sharpening surface/abrasives, and their sharpening angle (Typ. 15 deg., 20 deg. etc.). Pocket knife sharpeners are also rated according to their weight and portability.

If you are looking for a knife sharpener specifically for your pocket or outdoor knife, you will want one that is portable, reasonably priced, and made of hard material that produces a sharp edge quickly that will last a relatively long time.
Bench stones are portable, flat, single or double-sided sharpening stones. They are manually-operated whetstones or water stones, oil stones, or diamond stones.
are typically rectangular blocks. Most are double-sided (coarse and fine grits). They may be made of a natural material or they may be bonded abrasives (i.e.: ceramic, silicon carbide, or aluminum oxide). Bonded abrasives are more durable and provide faster blade sharpening than natural stones. They sharpen, hone, and finish a knife blade. However, they are better-suited to sharpening straight blades than serrated blades. It may also take practice sharpening knife blades to achieve a consistent angle.
are harder, very sturdy and durable, and less expensive sharpening stones. They require more time to produce a sharp edge and the oil makes the cleanup messier.
provide optimum hardness, sharpen faster, and are the most expensive type of sharpening stones. Their long-lasting durability makes them popular with outdoorsmen/women and professionals. With a slight bit of water, they quickly sharpen the dullest edges. Coarse diamond is often used to flatten/reshape uneven whetstones and oil stones.
Honing steels are primarily designed for the honing (straightening) your knife edge. Honing steels are lightweight, inexpensive, and portable, but they do not sharpen the blade, they just modify the edge of it. Some pocket knife sharpeners have honing steel rods in addition to blade sharpening angles.
Electric knife sharpeners quickly and relatively effortlessly sharpen your knife. They are not portable, however, since they require a power source. They are easy to set up and operate and produce the sharpest edge for straight knife blades. They are not an inexpensive alternative, nor are they generally used to sharpen serrated knife blades.
The most effective pocket knife sharpeners have a combination of abrasive materials for coarse, medium, and fine/ultra-fine sharpening stages.
Diamond is the hardest and the most durable material. It produces sharp edges quickly. Diamond sharpeners (diamond-coated steel plates or rods) are more expensive. They are best-suited for repairing/resetting your blade edge but can sharpen and finish edges as well.
Hunters and professionals prefer diamond sharpeners due to their durability and longevity. They do not lose their shape like whetstones and they require less maintenance.
Tungsten carbide is twice the strength of steel. It is preferred for sharpening very dull pocket knife blades.
Ceramic knife sharpeners are used for professional knife sharpening. They are preferred due to their water-, heat-, and rust-resistance. They are durable and made from high-grade corundum, silicon carbide, or alumina.
The abrasiveness (grit) is the coarseness/fineness of the sharpening stone. It denotes the materials ability to grind, shape, sharpen, or polish the blades edge. Hard abrasive surfaces (i.e.: diamond) sharpen the fastest. Tungsten carbide typically has medium-quality abrasiveness. Ceramic surfaces are fine and generally used to polish edges to razor sharpness.
Knife sharpening is done in stages. A coarse grit is used first for reshaping and to remove nicks. Medium grit is commonly used to sharpen blades. Fine to ultra-fine grit stones are used to finish and polish the knife blade.
Knife sharpeners that have adjustable angles are easier to use and guarantee a better result. To get the best result, know what the best sharpening angle is for your particular type of knife and blade before you start.
Approximate (consult instruction manual):
A good sharpener has safety features.
A barrier or guide protects your fingers during knife sharpening. Manual sharpeners without guides and barriers work better in the hands of more experienced knife sharpeners.
A solid, stable, and non-slip base keep the knife sharpener in place during sharpening. You dont want a manual knife sharpener to move, shift, or wobble as you pull the blade through the notch/slot.
Do not put too much pressure on the knife as you pull it through the sharpening notches toward you. Pull consistently and in deliberate and slow strokes.
Pocket knives are convenient, portable all-purpose tools. A dull pocket knife does not serve its purpose and can become a hazard if it slips when you apply pressure in an effort to cut. To ensure you get the very best results when you use it, as well as for your safety, regularly hone and sharpen it.
A well-maintained knife serves you well and lasts longer. Knife sharpeners remove nicks and reset and sharpen your blade to a razor sharp cutting edge. Portable, handheld, pocket sharpeners are the most convenient when youre in the field and are preferred by many hikers, campers, hunters, fishermen/women, etc. Countertop electric sharpeners are easy and fast, but lack portability.
The best pocket knife sharpener is lightweight, sturdy, compact, and sharpens straight and serrated knife blades. From those reviewed the Lansky PS-MED01 BladeMedic and Smiths PP1 Pocket Pal or Pocket Pal X2 comparably meet basic criteria and are ready-to-use anywhere, anytime.
Each of these sharpeners has (coarse grit) carbide and (fine grit) ceramic stones for sharpening and polishing, plus a retractable diamond rod for sharpening fish hooks and serrated blades.
Lansky additionally advertises a manufacturers warranty. The Smith Pocket Pal X2 offers additional survival features such as a flashlight, compass, whistle, and lighter/fire starter. All Lansky and Smith products include the required CA Prop 65 disclaimer.
I really love Lansky BladeMedics durable steel casing, although its quite heavy.
