What Tools Are Needed to Sharpen a Santoku Knife?

Before you begin sharpening your Santoku knife, it’s important to have the right tools handy. The most common tools used for sharpening are:

Whetstone Or Honing Rod

The first tool you can use to sharpen your santoku knife is a whetstone or honing rod. Both of these tools have their pros and cons, so it’s important to choose the one that best fits your needs.

Whetstones are more abrasive and better suited for dull blades while honing steel rods are gentler and meant for knives that just need a little bit of touch-up. Whichever one you choose, it’s important to follow instructions carefully, as improper use can end up damaging your blade.

Honing Oil

In addition to the whetstone or honing rod, you’ll also need some honing oil to sharpen your santoku knife. Honing oil helps to lubricate the blade as you sharpen it, making the process smoother and easier. It also prevents metal particles from clogging up your sharpening tool, which could hinder the effectiveness of its use. You can purchase honing oil online or in any store that specializes in kitchen knives.

Sharpening Stone

A sharpening stone is a great tool on hand when sharpening your santoku knife. These stones come in various shapes, sizes, and densities — each of which has its own unique sharpening properties. Different types of knives require different grades of stones, so it’s important to get the right one for your santoku knife.

When using a sharpening stone, remember to make sure there is plenty of lubrication (either water or oil) between the stone and the knife’s blade to prevent any damage. This method takes a bit of practice, but with some time and patience, you can sharpen your santoku knife like a pro.

Electric Knife Sharpener

For those who prefer the convenience of an electric knife sharpener, there are plenty of models on the market that are suitable for sharpening Santoku knives. Just make sure to read the instructions carefully before using it to sharpen knives, as each model has its own unique set of guidelines. Electric knife sharpeners can be a bit pricier than other sharpening tools, but they are much faster and easier to use.

Sharpening steel

A knife sharpening steel is another tool that can be used to open a Santoku knife. It’s important to choose the right for your blade, as different sizes of steel can produce different results. This method is best suited for honing and polishing already-sharp blades, as it doesn’t actually sharpen the dull blade but rather realigns knife edge.

These tools are just some of the options available when it comes to sharpening a Santoku knife. Depending on your budget and skill level, you can choose whichever tool best fits your needs and preferences.

How To Sharp A Santoku Knife?

Once you’ve gathered the right tools, it’s time to sharp your Santoku knife. Here are a few simple steps to get you started:

Step 1: Secure The Blade

The first step is to secure the blade of your Santoku Knife. If you’re using a honing rod, make sure it’s clamped securely in place before applying any pressure. For whetstones and sharpening stones, secure the blade with a vice or another clamp to ensure total control while sharpening. To secure the blade when using sharpening steel, simply hold the handle with one hand and rest the steel against an angled surface.

Step 2: Get The Angle Right

The next step is all about getting the perfect angle for your Santoku Knife. When sharpening any knife, it’s important to maintain an angle between 15 and 20 degrees so that you get the best results. You can use a sharpening stone to create the right angle and achieve a smooth edge. It’s also helpful to use a guide, like an angle cube, which will help you get it right every time.

Step 3: Keep It Even

Once you’ve got the right angle, it’s important to keep your strokes even while sharpening. Make sure each one is done with the same amount of pressure and that they are all in the same direction (usually downwards). This will help ensure a more consistent result with your santoku knife.

Don’t forget to keep checking back with the fine stone after every few strokes to make sure you are still maintaining the right angle.

Step 4: Test It Out

Once you’ve sharpened your Santoku Knife, it’s important to test it out before using it. Make a few small cuts and check the edge of such Japanese knives to make sure your efforts have paid off. If not, repeat steps 2 and 3 until the blade is as sharp as you want it. Remember to be patient and take your time—it’s worth it in the end! You can also try slicing a tomato, as this will give you an idea of how well your knife cuts materials.

Step 5: Clean And Oil

Once you’ve achieved the perfect edge, it’s important to clean and oil your Santoku Knife. This will help protect the blade from rust and keep the dull knives

in good condition for years to come. To clean your Santoku Knife, simply use a damp cloth and mild detergent. Make sure to avoid using abrasive cleaning agents, as these can damage the cutting-edge blade’s finish.

Once you’ve finished cleaning, dry your knife thoroughly with a soft cloth or paper towel, then lightly oil it with mineral oil or vegetable oil before storing. This will help protect the blade and keep it in good condition.

Step 6: Store Safely

After you’ve sharpened and cleaned your Santoku Knife, it’s important to store these serrated knives safely. Make sure you’re storing it in a safe, dry place and that the blade is covered to prevent any accidental cuts or injuries. Additionally, avoid storing your knife with other utensils, as this can cause them to become dull over time.
