How to Properly Use a Can Opener
A manual can opener is designed to cut around the rim of a sealed metal can so the lid can be removed. Most wheel-style manual openers use a cutting wheel and a feed wheel that grip the rim while you turn the handle.
How to use a manual wheel-style can opener
- Open the handles: separate the handles so the cutting wheel and feed wheel can fit around the can rim.
- Position the opener: place the cutting wheel against the top edge of the can and align the feed wheel with the rim.
- Clamp the handles: close the handles firmly so the opener grips the can.
- Turn the knob: rotate the handle in the direction specified by the opener while keeping the can steady.
- Continue around the rim: turn until the lid has been cut around most or all of the circumference.
- Remove the lid carefully: release the opener and lift the lid without touching sharp cut edges.
Can opener safety tips
- Keep fingers away from the cutting wheel and newly cut lid edges.
- Place the can on a stable surface before opening it.
- Do not force an opener that is slipping, bent or not gripping the rim properly.
- Inspect the cutting wheel periodically and clean away food residue after use.
- Discard damaged cans that are leaking, badly swollen or otherwise unsafe rather than trying to open them normally.
Different types of can and jar openers
Traditional manual can opener
This is the familiar wheel-style design that cuts through the metal lid around the can rim.
Safety or side-cut can opener
Some openers cut along the side of the rim rather than through the top surface. Follow the instructions for the specific design because the positioning can differ from a traditional opener.
Electric can opener
Electric models rotate the can or cutting mechanism automatically. They can be convenient for frequent use, but setup and cleaning instructions vary by model.
Pull-tab, jar and bottle opening tools
Not every product labeled as a multi-opener cuts sealed metal cans. Our 6-in-1 Jar & Bottle Opener Multi-Tool, for example, is designed for compatible jar lids, bottle caps, pull tabs and seals. It is not a traditional wheel-style can opener that cuts around a sealed can rim.

How to clean a can opener
Food and liquid can collect around the cutting wheel after use. Wipe or wash the cutting area according to the product instructions, remove trapped residue carefully and dry the opener before storage. Do not place an opener in the dishwasher unless the manufacturer states that it is dishwasher safe.
Frequently asked questions
Why does my can opener keep slipping?
The cutting wheel may not be aligned correctly with the rim, the opener may not be clamped firmly enough, or the mechanism may be worn or dirty. Reposition it and inspect the tool before applying more force.
Are all can openers used the same way?
No. Traditional top-cut, side-cut and electric openers use different mechanisms. Follow the instructions for the specific model.
Can a jar opener replace a can opener?
No. A jar opener is intended to add grip or leverage to lids. It does not necessarily include a cutting wheel for sealed metal cans.
What is the 6-in-1 opener best used for?
It is best suited to compatible twist-off jar lids, bottle caps, pull tabs, safety seals and similar everyday opening tasks rather than cutting sealed can rims.
