Sharpening a knife is sometimes perceived as the most difficult knife care task; and it probably is. Modern stainless steel is very hard and, when sharpened properly, will hold a good edge for a very long time. When sharpening a knife you must have a high quality sharpener that features a rough stock removal surface (preferably diamond abrasive) and a finishing surface of hard stone or ceramic abrasive. The diamond and ceramic materials will cut away the steel on the blade's cutting surface easily as these materials are harder than steel. A hard stone will also perform this task, but the stone is only slightly harder than the steel and so this requires more effort on your part. Most times, simply using a kitchen steel on your cutlery will be sufficient. See instructions below.
Remember, Keep your knife sharpened - a dull blade can be more dangerous than a properly maintained one.
Modern knife steel is very high quality material, but all metal will corrode through time. Occasionally oil the joints and springs of a pocket knife with a drop or two of oil. This will assure easier opening and closing and will prevent rust and lessen wear. Wipe the blades now and then with an oil-moistened cloth to prevent rust- especially if you live in a damp climate or close to the ocean. If your blade should get wet, dry it thoroughly. If your knife comes into contact with salt water or any substance you are not certain about, you should rinse it immediately with tap water, dry it and apply a light coat of oil. Do not store knives in their sheaths. The leather collects moisture and creates pits on the blade.
Check the locking notch of lockbacks regularly to ensure that it will work properly. Keep all sand and grit out of the knife. Keep the mechanisms clean. Remember to never rely on a folding knife to be permanently locked in position.
Do not use the cutting blade as a can opener, chisel, pry bar, screwdriver or for any heavy work for which your knife was not designed. Also, don't use the back of your knife as a hammer. It may break the springs, handles or pin.
Handles made of wood can be occasionally rubbed with furniture polish or oil. Brass can be polished with household brass polish.
Remember to keep your knife sharpened -- a dull blade can be more dangerous than a properly maintained one.
Knife sharpening grinds the blade while honing is done to keep the edge of the knife straight. Unlike sharpening, which removes material and actually sharpens the blade, honing is more of a “fine tuning” of the blade and should be done often. Most professional cooks "steel" their knives every day.
There are several ways to hone your knife, but they all share the same fundamental elements. Draw the entire blade across the honing steel at a 20 degree angle. Use a small amount of pressure evenly across the whole blade as it cuts across the steel.
Here is our recommendation on how to steel your blade: Hold the sharpening steel handle side up and rest the tip on a counter.
Hold your knife as you would to carve a turkey and slice against the steel at a 20 degree angle making sure to apply even but light pressure as you sweep across the entire blade surface on your way down toward the counter.
Repeat on the other side of the blade and alternate on each side several times. Don't grind hard against the steel or slap the blade against it. Listen for a light ringing sound as the blade moves across the steel.
At a certain point, honing the blade will become ineffective as the blade edge degrades from use (usually several months). At this point it should be sharpened using a sharpening stone or other sharpening tool.
First, obtain the correct sharpening tools to perform the task. Many of the sharpening kits on the market offer serration hones as options. Second, have the proper technique to use.
Most factory ground serrations will have the same angle as the plain edge portion (assuming the blade is partially serrated), which means in the neighborhood of 20 to 25 degrees.
Once everything is set up, you can begin the process. Using firm pressure, work the hone in a back-and-forth motion, perpendicular to the cutting edge. Every so often, stop and feel for a raised burr on the backside of the blade. Only move on to the next tooth when you see or feel a raised burr. Once you have completed sharpening the ground side of the blade, flip the knife over.
Y ou can learn to sharpen any razor on a stone, and if you have experience, or use the right sharpening system you will get very good results. The principle of grinding any knife is restoring the gross shape of a blade according to it's grind-type ; this is mostly done with machines such as grinding wheels. Grinding does not sharpen a knife. The principle of honing is to create a good cutting edge angle and the blade part directly adjacent to it, the relief. The relief is created by honing with a secondary angle on a stone until a burr appears, and subsequently create the primary angle (this is the cutting angle, which is somewhat greater than the secondary angle, but both under 25 degrees) to remove the burr. The relief/ secondary/primary angle principle makes the blade more resistant for less than delicate use.
When a knife is used, the edge eventually becomes dull. The edge will turn either to the left or right side depending on how you hold your knife when cutting. Quality knives with high carbon/molybdenum/vanadium alloy have elasticity and can easily be re-aligned by a sharpening steel. Do not use a diamond-coated steel or a pull-through manual or electric sharpening device for maintaining the edge. These devices will destroy your turned edge. They can be used to sharpen, but not for maintenance.
Place the knife blade against the tip of the sharpening steel at an angle of approximately 20 degrees. Pull the knife down and across the steel, describing a slight arc. Repeat this action on the back of the steel to sharpen the other side of the blade. Repeat steps 2 and 3 five to ten times, alternating the left and right side of the blade. It is very important to maintain the angle of 20 degrees and to run the full length of the cutting edge along the steel from the hilt to the tip of the knife. Speed of movement plays no part in this process.
