What To Look For When Choosing Knife Oil
In this part of the article, we will look at the most important factors to consider when choosing knife oil. Make sure to read this section before choosing a knife oil to ensure that your money is well spent.
Type of Knife
The first thing you have to consider is the type of knife you’re using. Is it a hunting knife, is it a spearfishing knife, or perhaps a folding pocket knife.
Even more important than the type of knife you’re using is the knife’s application. What are you going to use the knife for should be a number 1 factor to look at when choosing a knife lube.
If you want to buy lubricant for a kitchen knife that will be used indoors and will be in contact with food, a food-grade oil should be your first choice.
If you, however, want lube for an outdoor knife that will be used in extreme conditions, a heavy-duty, highly resistant lube should be your choice.
Folding knives require low viscosity oil that is thin enough to lubricate the pivot. You will want to use a lubricant that reduces friction and doesn’t attract dirt or debris.
So, before analyzing the features and properties of a knife oil, take a look at the knife you’ll be using it for first.
For outdoor hunting or pocket knives, you always want to use highly reliable and resistant lube. Since the knives will be exposed to extreme heat and cold, you want them to have high and low temperature resistance.
Some of the high-grade oils we reviewed can tolerate temperatures from -60 to 300 Fahrenheit. Those are the models that you should be looking for if you want to preserve your knives in snow or melting sun.
If you go scuba diving or spearfishing, you most likely have a knife that you carry on such trips. Those knives are going to be exposed to saltwater and a lot of moist air. If not lubricated properly with the right oil, your knives are going to rust and deteriorate quickly.
You need to make sure to pick a knife that has good corrosion resistance and saltwater tolerance. These properties in a knife lube are also essential if you are going to use your knife in the kitchen a lot.
Toxicity is definitely something to consider when choosing knife oil, especially if you intend to use your knives for cutting and preparing food.
Highly toxic lubricants that have a strong smell and fumes are hard to work with. You will often feel nauseated when working with them indoors. Try to pick a non-toxic lube that isn’t petroleum-based. It is better for the environment and your health.
If a knife lube isn’t toxic, that doesn’t mean that it’s food safe. For the knife that is used for preparing food, you need to carefully examine if the lubricant is food-grade. If you fail to do this and get an oil that isn’t a registered food-grade lubricant, you might put your health and the health of others at risk.
Food grade oil is tasteless and odorless. It doesn’t give you a headache while working with it and is safe if it accidentally comes in contact with food.
Even if the lubricant is food-safe, that doesn’t mean it should be used for food preparation. Food-safe oil means that if accidental food and lubricant contact occurs, no major health complications will happen.
The viscosity of the knife lube should be chosen based on the type of application. If you want to use the lube for folding knives and lubricating pivots, a light knife oil should be your choice.
It’s easier to work with a low viscosity oil since it will run and lubricate small and hard-to-reach parts by itself.
A high viscosity oil is often found on high-end lube models that are intended for heavy-duty outdoor knives that are supposed to be used in mud, rain, snow, salt water, and other intense conditions.
If you find one viscosity to be easier to work with than another, you can base your choice on that.
How easy is the application of the lubricant? Does it come in a bottle with just an ordinary cap to prevent spillage, or does it have a nozzle for precise dripping?
We always like to choose lubes that come in bottles with precision nozzles. Application is so much easier with them, and you can reach any place and lubricate any part of the knife you want with them.
If you find a high-grade knife oil that doesn’t have a good applicator, you can always buy the bottles with thin application nozzles additionally. We have reviewed such a bottle that is an excellent model that works with any type of lubricant.
Quality Of Lubrication
This may be the obvious one, but the quality of lubrication is the most important factor to consider and is what makes or breaks the knife oil.
A high-grade knife lube should be easy to clean up and won’t require excessive rubbing. The best knife lubes last a very long time and doesn’t dry out quickly.
If you pick a high-quality model you won’t have to lubricate your knife too often like with cheap models. The lubricant won’t harden over time and will reduce the friction of the locking mechanism.
How To Lubricate A Knife
Here is a step-by-step guide on how to lubricate your folding knife. You will need acetone or compressed air, knife lubricant, and a wiping cloth.
- Use acetone or compressed air to clean the knife from any old oil, debris, and grease.
- Lubricate the blade with a tiny drop of oil, and then lubricate the pivot with 2-3 drops of oil.
- Wipe down any excess oil, and you’re good to go!
If you’ve done everything right and used a high-grade oil, you should be good for at least a couple of months.
When using acetone, remember to only use 100% acetone since weaker nail polish models won’t remove the debris, oil, and dirt as well.
If you’re having trouble with lubricating knives, here is a video that might help you with the process.
