Heading out into the wilderness means packing gear that’s both reliable and versatile. One tool that often sparks debate is the humble can opener camping style. It might seem like a simple item, but choosing the right one can make a big difference in your backcountry kitchen. This guide will help you pick the best option for your trips and show you how to use it effectively, even if you forget to pack it.
Can Opener Camping
Let’s talk about why a dedicated can opener for camping deserves a spot in your pack. While many pre-packaged camping meals have moved away from cans, they are still a reliable source of food. They’re durable, non-perishable, and often contain ready-to-eat items like beans, fish, or fruit. A good camping can opener is designed to be more robust and easier to operate than your kitchen model, especially with cold or wet hands.
Why a Special Camping Can Opener?
Your home can opener likely requires a stable countertop and two hands. In camp, you might be balancing on a log or rock. Camping models are built for this. They are often more compact, have larger, grippier handles, and are made from materials that resist rust. Some even incorporate other tools, like bottle openers or small knives, saving space and weight.
Forgetting any tool can be a hassle, but there are ways to open a can without a dedicated opener. It’s good knowledge to have in a pinch. The classic method involves rubbing the can’s lid on a rough, flat stone like concrete or sandstone. Apply firm pressure and rub in a circular motion until the metal wears through. This takes time and effort, but it works.
- The Multi-Tool/Pocket Knife Method: Use the can opener attachment on a multi-tool. If you only have a knife, carefully puncture the lid’s edge and slowly saw around the perimeter. This is risky and can damage your blade, so it’s a last resort.
- The Spoon or Fork Method: A sturdy metal spoon can be used. Hold it with a firm grip and use the edge to repeatedly grind and puncture the lid’s seam until you can pry it off.
- The Fire and Water Method: This one requires caution. Remove the paper label and place the can directly in your campfire coals for a few minutes. The pressure from the heated contents will often blow the lid right off. Alternatively, heating the can in boiling water can weaken the seal.
Types of Camping Can Openers
Not all openers are created equal. Here’s a breakdown of the main styles you’ll find.
1. The Classic Manual Opener
This is the familiar design with a cutting wheel and a turning knob. Look for one with oversized, textured handles. Some have a magnet to hold the cut lid, which is a nice feature to avoid sharp edges falling into your food. They are reliable and easy to use.
2. The Side-Cutting or “Smooth Edge” Opener
These openers cut the can from the side, leaving a smooth, safe edge on both the lid and the can body. The lid also stays attached, so you can use it as a cover. They are slightly more complex but eliminate the risk of sharp metal.
3. The P-38 or P-51 Military Can Opener
A legend in minimalist camping. This tiny, foldable opener weighs almost nothing and fits on a keychain. It requires a bit more manual dexterity to use, but its reliability and near-zero weight make it a favorite among ultralight hikers and survivalists. The P-51 is a larger version with a bigger handle.
4. Multi-Tool Attachments
Many camping multi-tools and some pocket knives include a can opener. They are convenient because they’re part of a system you already carry. Test it before you rely on it; some are awkward to use compared to a standalone tool.
5. Electric or Battery-Powered Openers
Generally not recommended for true camping. They add unnecessary weight, depend on batteries, and can fail in damp conditions. Stick to manual tools for reliability.
Key Features to Look For
When shopping for your opener, keep these points in mind.
- Durability: It should be made of stainless steel or another tough, corrosion-resistant metal.
- Ergonomics: Large, comfortable handles are crucial, especially if you have limited hand strength or are wearing gloves.
- Ease of Cleaning: Simple designs with few crevices are easier to wipe clean in the field.
- Compact Size & Weight: It shouldn’t take up much space in your cook kit. The P-38 is the champion here.
- Additional Functions: A built-in bottle opener or a small knife can be very handy.
Step-by-Step: How to Use a Standard Camping Can Opener
Even a simple tool can be tricky if you’ve never used it. Here’s a foolproof method.
- Position the Opener: Place the cutting wheel on the top of the can, just inside the outer rim. The gear should grip the outer lip of the can.
- Secure the Grip: Squeeze the handles together firmly to puncture the lid with the cutting wheel.
- Turn the Knob: While maintaining pressure on the handles, rotate the turning knob. This will advance the cutter around the lid.
- Continue All the Way Around: Keep turning until you’ve cut almost all the way around. Leave a small section uncut so the lid stays attached and doesn’t fall into the food.
- Lift and Serve: Carefully lift the lid by the uncut section. You can bend it back completely or leave it as a partial cover.
Maintenance and Safety Tips
A little care goes a long way. After use, rinse your opener with clean water and dry it thoroughly before storing. This prevents food residue and rust. Occasionally, add a drop of oil to the moving parts if it starts to feel stiff.
Safety is paramount. The cut lid and the can itself will have sharp edges. Never run your finger around the rim. Use the can’s own lid or a spoon to remove contents. If you have a smooth-edge opener, this risk is greatly reduced. Always pack out your used cans; never bury or burn them in your fire pit.
Beyond Cans: Alternative Food Packaging
To reduce weight and waste, consider alternatives to canned goods. Dehydrated and freeze-dried meals are lightweight and only need hot water. Retort pouches (like those used for tuna or chicken) are soft, lightweight, and can be opened with a knife or scissors. They also pack out flatter than cans.
However, cans still have advantages for certain trips, like car camping or base camps where weight is less of a concern. Their durability is unmatched, and they provide a psychological boost—a can of peaches can feel like a luxury after a long day on the trail.
Making the Final Choice
Your choice depends on your camping style. For backpacking, a P-38 or a multi-tool attachment is ideal. For family car camping, a sturdy, easy-to-use classic or smooth-edge opener is perfect. Consider buying two: a tiny one for your backpack and a larger one for your main camp kitchen box.
Remember, the best gear is the gear you have and know how to use. Practice with your new opener at home before your trip. This ensures you’re comfortable with it and that it works properly. There’s nothing worse than struggling with a new tool when you’re hungry and tired at camp.
Investing in a good can opener camping tool is a small step that makes meal prep smoother and safer. It’s one of those items you might not think about until you really need it, and then you’ll be glad you packed the right one. By considering your needs and the options available, you can ensure you’re always prepared to open up a hot meal, no matter where you set up camp.
