The Best Can Opener Cooks Illustrated, Buying Guide

In contemporary usage, there is no significant functional difference between a can opener and a tin opener. Both terms refer to tools used to open metal cans. The distinction lies mainly in regional language preferences:

• Can Opener: More commonly used in American English.
• Tin Opener: More commonly used in British English.

Historically, "tin opener" referred to tools for opening tin-plated steel cans, but as can materials evolved, the terms have become interchangeable.

Is an electric or manual can opener better?

The choice between an electric and manual can opener depends on various factors:

• Electric Can Openers:

  • Pros: Require minimal effort, ideal for people with limited hand strength or mobility issues, often come with additional features like built-in knife sharpeners.
  • Cons: Require a power source, take up more counter space, generally more expensive, more parts that can break or malfunction.

• Manual Can Openers:

  • Pros: Simple design, easy to clean, portable, no electricity needed, generally less expensive.
  • Cons: Require physical effort, can be difficult for people with arthritis or hand strength issues, blades and gears can wear out over time.

What is the best alternative to a can opener?

When a can opener is unavailable, several alternatives can be used to open a can:

• Kitchen Knife: Carefully puncture the lid near the edge and cut around it. Use caution to avoid injury.
• Tin Snips or Strong Scissors: Gradually cut through the can’s side, being mindful of sharp edges.
• Screwdriver and Hammer: Place a flathead screwdriver on the can’s edge and gently tap it with a hammer to pry open the lid.
• Multi-tool with Can Opener Attachment: Many multi-tools include a can opener blade that can be used in a pinch.

How to do the best can opener?

Using a can opener correctly ensures safety and efficiency. Here’s how to use a manual and electric can opener properly:

• Manual Can Opener:

  1. Place the cutting wheel on the can’s edge and clamp the handles together to pierce the lid.
  2. Turn the knob to rotate the cutting wheel around the can’s rim.
  3. Once the lid is cut, carefully lift it away, using caution to avoid sharp edges.

• Electric Can Opener:

  1. Position the can under the cutting blade.
  2. Press the lever or button to start the motor.
  3. The opener will automatically rotate and cut the lid. Once complete, lift the lever to release the can.

Why don’t manual can openers work anymore?

Manual can openers may stop working effectively due to several reasons:

• Dull Blades: Regular use can dull the cutting blade, making it difficult to pierce and cut through can lids.
• Rust or Corrosion: Exposure to moisture can cause rust or corrosion, especially if the opener is not properly dried after use.
• Wear and Tear: Over time, the gears and handles can wear out, leading to decreased functionality or complete failure.
• Improper Use or Maintenance: Not using the opener as intended or neglecting regular maintenance can shorten its lifespan. Proper care includes cleaning after each use and occasional lubrication of moving parts.

By understanding these factors, you can better maintain your can opener and ensure it remains functional for a longer period.
