About Electric Can Opener Leaving Sharp Edges

Most electric can openers cut down through the top of the lid, which leaves sharp edges on both the lid and the can rim. That's normal for this design. If edges are jagged or torn, the cutting wheel may be dull, dirty or not seating properly on the rim.

Smooth-edge openers cut through the side seam instead and leave no sharp edges at all.

Why it happens and how to fix it

Top-cut design

Sharp lids are expected with top-cutting openers. Lift lids with the magnet and dispose of them carefully.

Dull or dirty cutter

Clean the cutting wheel and gear of food residue. Some models have replaceable cutters.

Poor seating

Make sure the can rim sits fully under the cutter before pressing the lever.

Dented cans

Dents near the rim cause skipping and jagged cuts. Open dented cans with a manual opener.

Smooth-edge alternative

Side-cutting smooth-edge openers leave blunt edges and let lids sit back on the can.
