Go for proficient enough— not perfection!

A knife that'll hands piece through food is abrupt plenty. The lycopersicon esculentum test (beneath) will tell y'all when a knife is ready for food prep.

Follow Photos 1 – 3 for the three-stride sharpening process. After sharpening and before any food prep, wipe off the blade with a cloth to remove any metal filings.

Use a steel—oftentimes!

Steeling restores the edge
Chefs and meat cutters frequently pause and "steel" their cutting edges. Steeling doesn't sharpen an border; it straightens it.

Cutting-Edge Tips From Joe

Cut boards:
Drag the tip of your pocketknife across your cutting board. If the surface doesn't scratch, it'due south too hard and it'll dull your knife in no fourth dimension. Some plastics and certainly glass and laminate surfaces won't pass the exam, even if they're called "cut boards" on the label.

Acidic foods:
Rinse knives after cut acidic foods like citrus fruits or pickled goods. Acid promotes corrosion right at the cutting border, even with stainless steel. Dry them right afterward.

Cleaning:
Don't ever throw knives in a dishwasher. Wooden handles will become ruined, and even stainless steel blades volition corrode and get dull. Instead, wash your knives by manus and dry them off right away.

Protect the edges:
Don't just toss unprotected knives into a drawer. Either employ a knife block or stow them abroad with blade protectors. Simple paper-thin sheaths held together with duct tape volition do the job.

Avert bones:
They'll dull fifty-fifty a high-quality knife. Electric sharpeners: Don't e'er use a cheap electrical knife sharpener, especially the ones found on electric can openers. They'll do more harm than good. If you love gadgets, spend at to the lowest degree $125 for a decent electric sharpener. (You'll still take to steel your knives, by the fashion.)

Other knives:
"I acuminate all knives the same fashion—hunting knives, fillet knives, what ever. Keep a mini sharpener in your tackle box and use the aforementioned techniques."

Sharpen each scallop with the steel. Friction match the angle of the scallop and push the knife away from yous. Practise each scallop ii or three times, then move on to the next.

Photo 2: Create the burrs

Elevate your fingertip over the flat side of the pocketknife. If you feel burrs along the whole length, skilful. If any scallops are missing burrs, flip the knife over and striking those again.

Shut-up of burrs

Burrs signal the scallop is sharp.

When you're satisfied, pull the apartment side of the knife forth the rod to knock off all the burrs. Now your knife is sharp.

Serrated knives can be sharpened, simply unlike ordinary knives, they need a diamond-coated steel that's properly sized to match the knife.

If you desire to master the technique, accept your serrated knives to a knife or cookware store and ask to have your knife matched to the right diameter diamond-coated steel.
