In any kitchen—home or commercial—a can opener does more than open cans. It affects prep speed, safety, and workflow consistency. A weak opener slows prep, increases the risk of cuts from sharp lids, and tends to fail quickly under volume—especially when opening large cans.
This guide explains what a can opener is, how different designs work, and how to choose between manual and electric models. It also covers smooth-edge vs traditional cutters, commercial-grade features, and real-world buying criteria so you can select a can opener that matches your usage volume, staff comfort, and long-term reliability needs.
What is a can opener?
A can opener is a manual or electric kitchen tool used to cut and remove the lid from sealed metal cans. It’s used in home and commercial kitchens to access canned food safely, efficiently, and with minimal risk of injury.
Quick answer:
If you only open a couple of cans now and then, a basic manual opener is fine. If opening cans is part of your routine—or your hands get sore—an electric opener or heavy-duty manual model will be easier and more comfortable over time.
In high-volume prep kitchens, we see can openers fail most often when cutting wheels dull, gears slip under load, or mounting loosens during repetitive #10-can opening—issues that don’t show up in light home use.
A Brief History of Can Openers
- 1810 – The tin can is patented, accelerating canned food storage, though early cans are opened with knives, chisels, or tools.
- 1858 – Ezra Warner patents the first dedicated can opener, effective but awkward and unsafe for home use.
- 1870 – William Lyman introduces the cutting-wheel can opener, forming the basis of modern designs.
- 1925 – A second serrated “feed wheel” is added, making can openers easier, safer, and more practical for everyday use.
- 1950s – Electric can openers become widely adopted in consumer kitchens.
This evolution explains why modern can openers are safer, faster, and more ergonomic than early designs—supporting both home cooks and high-volume kitchens.
Most buying decisions come down to how often cans are opened and how much effort the user can comfortably apply.
Types of Can Openers
The two main types of can openers are manual and electric. Before choosing a can opener, it helps to understand the two main categories and how they differ in effort, speed, and durability.
1. Manual Can Openers
Manual can openers use a hand-turned cutting wheel to pierce and cut the lid. They’re simple, durable, and widely used in both home and commercial kitchens.
Best for: homes, travel, emergency kits, and light to moderate daily use.

Recommended Example (Manual)
1. Edlund — No. 1 Manual Can Opener (Commercial, Gear-Driven)
Best for High-Volume Kitchens Opening #10 Cans All Day Without Slipping or Stalling
The Edlund No. 1 is a heavy-duty, gear-driven manual can opener built for nonstop commercial prep. It’s a staple in restaurant kitchens because it powers through #10 cans with consistent cutting performance, day after day, without the wobble or fatigue you get from lighter-duty openers.
Why It Works for #10 Cans
Big cans expose weak mechanisms fast. A gear-driven system keeps steady pressure on the can rim, helping the blade track smoothly so you get clean cuts with fewer stalls, slips, or jagged edges—especially when staff are moving quickly during prep.
Operational Highlights (Edlund No. 1)
| Feature | What It Does | Why It Matters in Service |
|---|---|---|
| Gear-driven, manual operation | Uses gearing to maintain cutting force | Smoother, more consistent cuts on large cans |
| Commercial #10 can capability | Designed for institutional-sized cans | Handles high-volume prep without struggling |
| Heavy-duty build | Built for durability under daily use | Longer service life, fewer replacements |
| Consistent cutting performance | Helps the blade track evenly | Cleaner openings, less mess and rework |
Pros and Cons
| Pros | Operational Benefit | Cons | Operational Tradeoff |
|---|---|---|---|

Recommended example (Electric):
1. Edlund — 203/115V Electric Can Opener (2-Speed)
Best for High-Volume Prep Stations That Need Fast, Low-Fatigue #10 Can Opening
The Edlund 203 is a commercial electric can opener designed for busy prep lines where opening cans is constant—not occasional. With a two-speed motor and commercial build quality, it’s built to move through #10 cans quickly and consistently while reducing strain on staff during long prep runs.
Why It Works for High-Throughput Can Opening
When you’re opening dozens of cans per shift, manual crank time adds up—and so does fatigue. An electric drive keeps cutting pressure steady, helps the blade track cleanly, and speeds up repetitive tasks. The two-speed control also gives you flexibility: faster operation when you’re in a rhythm, and a slower option when you want more control on tougher lids or when training new staff.
Operational Highlights (Edlund 203)
| Feature | What It Does | Why It Matters in Service |
