When it comes to knowing how to clean a pocketknife, let us guide you on the methods to get your backcountry blade back to its best. Knife envy is not just the preserve of whoever’s tagging along with Crocodile Dundee for the day. You too can turn green with jealousy when your camping buddy pulls out a shiny new pocketknife and you realise your once beloved old thing looks like something you’ve just found in a muddy puddle during a hike.

However, there’s no reason that repeated use should render your pocketknife dulled and dirty. Giving it a thorough clean every once in a while will make a world of difference. A grimy pocketknife is not only unhygienic but excessive dirt can clog up the mechanism, meaning that it may not close properly, which is potentially dangerous.

How to clean a pocketknife: regularly give the exterior a good clean

When you come to wash your camping utensils after a scrumptious meal, it’s a good time to give your pocketknife the once over.

Open up the blade and take a toothpick to all the more intricate parts of the knife, such as the pivot point and screwheads. Lever any gunk or lint out of the crevasses. Another trick you can use here to fight off stubborn dirt is using a compressed air can and blowing into the tiny gaps. 

Next, apply your cleaning product onto the knife and scrub with an old toothbrush to remove any tough bits of dirt. Finally give it a good wipe down with your cloth, being careful of the blade. This should be enough to keep your knife relatively clean during your camping trips.

For a multitool, you’ll want to follow the same principles before pulling each tool out one at a time. Give them a thorough scrub with the toothbrush, before a more general clean with a cloth.

Rinse the soap or cleaning products off your knife and then dry it using a towel.

Every now and again, your pocketknife is going to need some additional TLC. This is where the deep clean comes in.

1: Disassemble

First things first, check your manufacturer’s warranty, as taking your knife apart can void this. If all is well and good regarding warranty, proceed to take the screws out of your pocketknife. They’re only tiny little things, so make sure you store them somewhere safely. If you’ve never taken your knife apart before, you may be surprised at just how grimy the out-of-sight parts of it are.

2: Clean the individual components

Using your soap or cleaning spray and your toothbrush, go to work on all the individual components of your knife. Use all the tools in your arsenal. Toothpicks are great for getting the gunk out of intricate spaces, while cotton buds can be useful for cleaning out the circular hinge holes and for general polishing. Don’t forget it’s not just the main parts of your knife that need a good clean, the screws and washers should also be given a quick scrub.

3. Dry and reassemble

The metal in your knife is prone to rust when in contact with water and oxygen, so it’s absolutely essential to dry your components thoroughly before reassembling. This is another good time to utilize your compressed air can, which can be used to blow through the little screw holes and hinge points to ensure there’s no residual moisture.

When it comes to reassembly, it’s usually easier to put the knife back together in the open position.

4. Apply lubricant to the pivot

The final step is to add some lubricant to your knife’s pivot and any other moving parts to give you a smooth action when you flip the blade open and closed. The lubricant you choose will depend on how you use your knife. If you regularly use your tool to prepare food for your camping meals, a food-based lubricant is probably best, such as vegetable oil. The rule here is to just use a little, before working it in by flexing the pivot to check the action. Wipe away any excess oil with a paper towel and you’re done!
