Filing pocket knives is similar to filing other sorts of knives, but due to its size, the method is a little different. Conventional electric filers don’t always work because the blade is smaller than customary knives. Refer to the manuals for any electric filer to find out if a smaller knife can be placed in the machine. Furthermore, as the handle is on. A pocket knife is best filed with a stone and steel.
1. Reveal the knife and lubricate it
You will want to start with a good lubricant on the knife edge. Reveal the knife and lock it in the open position. With a cotton ball, apply a manufactured recommended lubricant on the knife edge. Find what angle will work for your needs by checking with the manufacturer, or consult a professional knife sharpening shop. If you do not have this type of access, use a 17 degree angle, as this is a nice, safe average. grab the handle tightly before placing the blade to the stone.
3. Start filing
Drag the blade across the stone in the opposite direction that you would use the blade. Typically, this means you are pushing the blade away from you. File only one side at a time.
4. Check for burrs
After the first side is done, check for burrs by pushing your thumb on the blade. If there are no burrs, the edge needs to be filed again. The burrs must be there. You will get rid of them later, during the polishing process.
5. Sharpen the other side
Flip the blade over and drag it across the stone in the same manner. You are trying to edge each side independently. Don’t fret about the point of the blade; if you file both sides at the same angle the point will come about naturally. Again, check for burrs to make sure you are truly cutting into the blade and creating a sharper knife.
6. Employ a steel
Finally pass the pocket knife along a steel. This polishes the edge and cleans off all those burrs. This ultimate step is necessary for the knife because the burrs will catch on the casing of the pocket knife, effectively unsharpening the blade more quickly than usual.
As with every knife edging process, practice makes perfect. Practice, practice, practice and ask for help if you need it. By working thoroughly and practicing on some knives that are less important to you before moving on to your most valuable pocket knives, you can produce sharp, professional edges.
