Cleaning and Lubrication of Shredder Blades

Although the internal structure of the shredder blade is not too complicated, the shredder blade may hinder the function of the knife, especially near the pivot and locking area. In the case of a pivot, the cutter may open more slowly or more difficultly, and accumulation in the locked area may prevent the cutter from being locked open or closed, which may cause serious injury.


Long-term use and exposure to hard materials or saltwater may even permanently damage the shredder blade. For these reasons, regular maintenance of pocket knives is required.


We recommend cleaning and lubricating once a month. This is also a good time to check for other potential problems with the knife, such as corrosion of the shredder blade or internal components, and loose screws.


Step 1: Clean


As mentioned above, you will need to pay attention to the pivot and locking surface of the shredder blade. If you only have some lightweight lint, you can usually use a toothpick, screwdriver, or other probes to remove it. If you have sand and gravel, you may want to use warm soapy water and then use a bristle brush (I like to use a Japanese toothbrush). If you really want to go this way, please continue to brush off the entire blade, including the shredder blade and handle scale.


Usually, this is all that is needed to restore the handle scale to its original gloss. Don't be afraid to get wet inside, remember that it is the more important cleaning area. Just make sure to rinse well.


If neither of these two methods can remove the stickiness and dirt remaining on the blade, try putting the shredder blade in a bowl of warm water. This will help reduce dirt.


If your shredder knife is still hard or difficult to open, you may need to disassemble the knife for in-depth cleaning, and we will not cover it in this article. You may need special tools, and the process will vary depending on the knife used.


Many tool manufacturers will also tell you that disassembling the tool will void the warranty. If you use any kind of wet cleaning knife, please make sure to wipe off the excess water and let the knife air dry for at least 15 minutes before lubricating it. Even if your knife uses stainless steel, it may be corroded.


Step 2: Choose a lubricant


The shredder knife is a system with moving parts. As with any such system, it must be lubricated, especially the mating surfaces, such as pivots, locking surfaces, or slide rails.


The more popular lubricants are petroleum-based wetting lubricants and are basically the same as gun lubricants or sewing machine oils, although they claim to have characteristics that make them superior to their competitors.


Dry lubricants are usually based on PTFE (polytetrafluoroethylene) and tend to attract less lint. They usually enter the spray cans in the form of spray cans or grease pipes, and dry on the surface, leaving a protective lubricating film. A few examples are Super Lubricant, Miltec, or Chris Reeve fluorinated grease.


Step 3: Apply lubricant


When using lubricants, your mantra should be "a little bit goes a long way." Open the shredder knife and put a drop or two of oil on the pivot (if using PTFE dry lubricant, spray a little oil).


Then start to rotate or rotate the shredder blade (open and close repeatedly) to use the lubricant. Your goal is to use only enough lubricant to spread to the entire target area (usually a pivot or locking surface) without penetrating the shredder blade.


Excessive lubricants, especially oily wet lubricants, can actually attract pocket lint and other substances. This means you will have to clean the knives more frequently.


If the blade of the knife is made of high carbon steel (high carbon stainless steel or real carbon steel), you may also want to use a preventive lubricant on the blade itself.
