When it comes to maintaining the razor-sharp edge of your knives, several factors come into play – the frequency of use, the care you provide, and the types of items you’re cutting. While the longevity of a knife’s sharpness varies, Japanese knives, known for their exceptional craftsmanship and high-quality materials, generally outperform their Western counterparts in edge retention.

In rigorous testing, Sakai Kyuba knives have proven their mettle, surpassing the performance of even more expensive brands. For the average home cook who prepares meals 5 times a week, we estimate that Seki Kyuba knives will maintain their razor-sharp edge for an impressive 7-10 months. This is a testament to the skill and dedication of our master blacksmith, who combines centuries-old traditions with innovative techniques to create blades of unparalleled quality.

However, it’s important to recognise that no knife, no matter how expertly crafted, can stay sharp indefinitely. Regular use and the demands of everyday cooking will eventually take their toll on even the finest blade. But fear not – we’ve got you covered.

To ensure that you can always enjoy the precision and ease of a sharp knife, we offer a range of top-quality sharpening stones. With just 5-10 minutes of your time, you can restore the edge of your Seki Kyuba knife to its original glory, right in the comfort of your own home. Our sharpening stones are carefully selected to work in harmony with the steel of our blades, making the process simple and effective.

For those who prefer to leave the sharpening to the professionals, we’ve curated a list of trusted knife sharpening services. 

If you can’t afford or do not want to commit to buying a set immediately, the single most important tool in your kitchen is The Gyuto – The Chef’s Knife. It’s the workhorse you reach for most often. Investing in one great knife now will change your cooking for life and make it a pleasure rather than a chore. Our Sakai Kyuba Gyuto can do 99% of your kitchen cutting. Another option for a daily knife is Santoku knife. However, if you’re looking for an ultimate experience, you should consider investing in a 3-pieces set; including The Petty (Paring/Utility Knife), Nakiri (Veggie/Fruit Knife) in addition to The Gyuto (The Chef’s Knife).

It depends on the steel you’ll go for. Usually, stainless knives are easier to maintain. Luckily, Seki Kyuba have the best of both world – they have a high carbon content that helps maintain the edge, yet, with their HRC Rockwell 62-63 scale, they’re stainless which makes them easy to maintain.

Like most equipment, knives need a little love and care. Here are a few tips to help you get lasting service from your Seki Kyuba knives:

• Keep your knife dry – the entire knife, not just the blade.
• Keep your knife sharp. Remember, a sharp blade is safer than a dull one. Use only professional sharpening tools and whetstones.
• Do not use the cutting blade as a can opener, chisel, pry bar, screwdriver or for any heavy work for which your knife was not designed. Also, don’t use the back of your knife as a hammer. It may break the springs, handles or pin.
• Avoid prolonged immersion in liquids (water, solvents, etc.). This can have a detrimental effect on not only the metal parts, but handles made of wood or other porous materials as well. Before using your knife on food items, wipe clean with alcohol, or wash with hot soapy water and rinse clean. 
• For carbon knives, periodically apply a small amount of lubricant to the working parts of the knife, particularly the pivot points of a folding knife. Then apply a thin film of lubricant to the entire surface of the blade. This will help prevent surface oxidation and corrosion from moisture.
• Sharpen your knives using high-quality sharpening tools such as natural stones or whetstones.

Whether Japanese, Swiss or German, each type of knife has been influenced by its culture. The Japanese believe in need of having a perfect tool for an explicit purpose, and as such have many specific knife shapes for specific tasks. Meanwhile, Germans value versatility and durability in their culinary efforts and therefore German knives are characterised by being good in many different undertakings. In the end, each knife has its own strengths and weaknesses. It’s not that one style of knife is better than the other — it’s just a matter of use and preference (of course as long as the knife is made from high-quality materials).

If you’re just the beginner or an occasional user (We are guilty as charged! We usually leave this job to our partners), we suggest getting a combination whetstone, something between 1000 and 6000 grit like King 1000/6000 combo waterstone. These two stones and an inexpensive flattener will carry you a very long way. Add other stones or stropping supplies in the future as you learn. We think most new sharpeners should stay away from stones coarser than #1000 until they develop a technique they are comfortable with unless there is a very specific project in mind.
