What You Need to Sharpen a Multi Tool Blade

Sharpening a multi tool blade is an important part of maintaining your tools and ensuring they are in good working order. To get the best results, you need to have the right materials and tools on hand.

The most important item for sharpening a multi tool blade is a whetstone. This stone is used to grind away at the metal of the blade, creating an edge that can cut through material with ease. It’s important to choose one that has two different grits – coarse and fine – so you can work up from rough grinding to finer honing as needed.

You will also need some honing oil or water when using your whetstone. This helps keep the surface lubricated while you sharpen, which prevents it from becoming clogged with metal particles and ensures even grinding across the entire length of the blade. You should use enough oil or water so that it covers about half of the stone’s surface area when in use.

Finally, it is always wise to wear protective gloves when handling any kind of sharpened blades or stones during this process, as accidents can occur easily if proper care is not taken.

Sharpening your multi-tool blade is a simple task when equipped with the proper tools and a little patience. Now let’s look at how to do it.

How to Sharpen a Multi Tool Blade

It’s not hard to do, but it does take some time and careful attention to the small details. Here are the steps you need to take:

1. Position the Blade on the Whetstone: The first step in sharpening your multi tool blade is positioning it correctly on the whetstone. You want to make sure that the edge of your blade lines up with one side of the stone so that when you start sharpening, you can move along its length evenly. Make sure there’s enough space between your fingers and the blade so that you don’t accidentally cut yourself while working.

2. Start Sharpening: Once your blade is properly positioned on the whetstone, begin moving it back and forth across its surface in a consistent motion – this will help create an even edge as well as remove any burrs or nicks from previous use. Use light pressure when doing this; too much force could damage both your knife and whetstone.

3. Number of Strokes Needed: Depending on how dull or damaged your multi tool blade is, you may need anywhere from 10-20 strokes per side before it starts looking sharper again – if necessary, repeat these steps until desired results are achieved (but be careful not to overdo it.). If done correctly, each stroke should only take a few seconds; anything longer than that indicates either improper technique or excessive pressure being applied during the sharpening process.

After completing all necessary strokes per side of your multi tool blade (and ensuring they were done evenly), finish off by wiping down both sides with a clean cloth. This will help remove any excess metal shavings left behind after successfully completing the sharpening process. Finally, store away safely for future use – preferably somewhere out of reach from children or pets who might accidentally hurt themselves if mishandled improperly.

With the right tools and technique, sharpening a multi tool blade can be done quickly and easily. Now let’s look at some tips to help you get even better results when sharpening your blades.

Key Takeaway: Sharpening a multi tool blade requires patience and attention to detail. Follow these steps: Position the blade on the whetstone, move it back and forth across its surface with light pressure, 10-20 strokes per side until desired results are achieved, wipe down both sides with a clean cloth and store safely.

Tips for Sharpening Multi Tool Blades

Here are some tips to help you get the best results when sharpening your multi tool blades:

1. Use Honing Oil: Before beginning, make sure to use honing oil on the blade. This will help lubricate the blade while sharpening and prevent any damage from occurring during the process. It also helps keep metal particles away from other parts of your tool or work surface, which can cause rust or corrosion over time.

2. Clean After Each Use: After each use, take a few minutes to clean off any debris or dirt that may have accumulated on the blade before putting it away for storage. This will ensure that no dirt gets into the crevices of your multi-tool and prevents rusting over time, as well as making future sharpening easier and more effective.

3. Replace When Necessary: If you find yourself having difficulty getting a good edge with repeated sharpening attempts, then it may be time to replace your blade instead of continuing to sharpen it further down its lifespan until eventually becomes too dull even after multiple tries at honing it back up again.

4 . Sharpen Regularly: To maintain optimal performance levels with minimal effort , regular maintenance should be done by regularly checking if there’s any need for resharpening. Doing this ensures that you don’t wait too long between sharpenings, leading to excessive wear on both tools and blades alike.

Considering investing in a sharpener is still worth considering if you plan on doing lots of heavy-duty cutting tasks with your multi-tool. Manual sharpeners are usually much cheaper than their electric counterparts but still provide excellent results without risking damage due to overheating or grinding too quickly.

Key Takeaway: Regularly clean, sharpen and replace multi tool blades to maintain optimal performance. Use honing oil when sharpening, clean after each use and consider investing in a manual sharpener if you do lots of cutting tasks.


With the right tools and techniques, you can easily sharpen multi tool blades to keep them in top condition. Sharpening a multi tool blade is not as difficult as it may seem at first, but if done incorrectly, it could damage your blade. Be sure to follow all safety precautions when sharpening any type of blade and use the correct tools for the job. With these tips in mind, you’ll be able to sharpen your multi tool blades like a pro!
