Why sharpen a manual can opener?
A manual can opener is a basic kitchen tool that requires little maintenance, but after a while, it can become dull and inefficient. Dull blades might not cut the can lid properly, leading to jagged edges, which can be dangerous. A sharp manual can opener is essential to open cans smoothly and safely, without risking injury.
What you’ll need to sharpen a manual can opener
Before sharpening your manual can opener, you’ll need to gather some basic supplies, such as a sharpening stone or honing rod, a clean cloth, and lubricating oil. Sharpening stones come in various materials, such as ceramic, diamond, or natural sharpening stone. Consider which one is best for your particular can opener and budget.
How to sharpen a manual can opener with a sharpening stone
To sharpen your manual can opener using a sharpening stone, start by cleaning your can opener with a damp cloth to remove any debris. Then, hold the sharpening stone firmly in place with one hand and use the other hand to guide your can opener across the stone at a 20-degree angle. Repeat this motion several times, flipping the can opener blade over each time for even sharpening, until you can feel the blade is sharp enough.
How to sharpen a manual can opener with a honing rod
If you prefer to use a honing rod, make sure it’s the same size as your manual can opener blade. Wet the honing rod with some lubricant oil and, holding the rod vertically, insert the tip of your can opener blade into the groove of the rod. Then, gently pull the blade towards you while maintaining a 20-degree angle. Repeat this motion several times, alternating the side of the blade until it’s sharp enough to cut the can lid effortlessly.
Maintaining your sharpened manual can opener
After you’ve sharpened your manual can opener correctly, you should take steps to maintain its sharpness. One way to do this is to keep it clean and dry, and lubricate the blade with food-grade oil regularly. You can also sharpen your manual can opener blade once a month if you use it frequently. Last but not least, keep in mind that a well-maintained sharp blade will not only make your life easier but also ensure safe and seamless can opening.
