Master the Crust: The 10-Inch Precision Bread Knife That Never Shreds The Artisan Solution for Serious Bakers If you have ever struggled with a standard 8-inch bread knife while tackling a wide, crusty sourdough or a homemade miche, you know the frustration of 'shredding' rather than 'slicing.' The I.O. Shen 10 in. (250mm) Bread Knife is the professional-grade answer to the artisan loaf. Its extra-long blade allows for a full, sweeping motion that clears the largest loaves in a single pass, ensuring clean, uniform slices every time. The Science of the Steel Unlike many serrated knives that use cheaper, softer alloys, I.O. Shen utilizes a proprietary VG-10 steel blend. This is a high-carbon super steel that offers outstanding edge retention. Because serrated blades are more difficult to sharpen at home, I.O. Shen prioritized the durability of the points. Note: This is the only knife in the I.O. Shen collection that does not feature the signature Triplex steel construction. The reason is intentional: a serrated blade requires the uniform hardness of their specialized VG-10 blend to maintain its aggressive cutting profile without the need for frequent professional servicing. A Versatile Japanese Slicer While designed for bread, the Japanese engineering behind this knife gives it a dual identity. The bow-shaped blade and surgical-grade serrations make it an exceptional choice for slicing through beef, roasts, and large poultry. The points bite into the protein while the 10-inch length allows for the long, clean draws required for thin, catering-style slices. Whether you are a professional chef or a dedicated home cook, the I.O. Shen 1027 is a high-performance tool that replaces two knives with one superior instrument. Learn More

The I.O. Shen 6.7 in.(170mm) Maoui Deba is not a traditional Japanese Deba design as the edge is on both sides of the blade. With this style get the great benefits of a knife that can handle work on fish like filleting, gutting, and gill removal with a more durable edge and premium stainless steel. Note that the steel that forms the scrimshaw design on I.O. Shen knives is welded to the tang and not just some type of silver paint. Tri-Ply steel with VG-12 core 1.7 mm spine thickness 12.13 inch overall length 8.5 ounces (240 grams) Made In Tai Wan Learn More

The I.O. Shen 6.7 in. (170mm) Oriental Slicer has a smaller handle then other knives in the I.O. Shen line that is to give the user more finger clearance between the cutting board the the handle making this a good knife for prepping onions or mincing garlic. This is not just a good vegetable knife but is naturally a slicing knife and is thin enough to slice fillets of fish or prepare sashimi. Learn More

The I.O. Shen 6.3 in (160mm) Santoku is well suited to heavy vegetable prep as the flat edge makes near full contact with the cutting board allowing for cleaner chopping and mincing. The flat edge of the Santoku is also beneficial for sharpening on whetstones as the knife will make more contact with the stone as you pass it along the stone. Learn More

The Professional’s Heavyweight: Precision Slicing with I.O. Shen’s Proprietary Triplex Technology In the high-pressure environment of a professional kitchen, your chef knife isn't just a tool—it is an extension of your hand. The I.O. Shen 9.4-inch (240mm) Chef Knife is engineered specifically for those who demand more from their cutlery. This isn't a standard stamped blade; it is a product of advanced metallurgical engineering designed to solve the age-old conflict between hardness and brittleness. At the heart of this knife is I.O. Shen's signature Triplex Steel Technology. By sandwiching an ultra-hard VG10 steel core (Rockwell 62°) between two layers of softer, more flexible stainless steel (Rockwell 10°), I.O. Shen has created a blade that holds a razor-sharp edge significantly longer than Western counterparts while maintaining the structural integrity to resist chipping. The 240mm length provides the necessary 'heft' and blade real estate for heavy-duty prep work—from breaking down large proteins to julienning dense root vegetables. Unlike the standard 8-inch (210mm) models, this 9.4-inch version offers increased blade depth. This provides critical knuckle clearance and a more substantial feel for chefs with larger hands, ensuring comfort during grueling double shifts. The weight distribution is meticulously calibrated to provide a 'rocking' motion that feels effortless, reducing wrist fatigue and increasing precision. Learn More

The I.O. Shen 8 in. (210mm) Gyuto is the all purpose knife in the I.O. Shen collection. This Gyuto has less camber or curve to the edge then most knives making it great for a cook who slices through their food rather then rocking and chopping. The flat edge on this Gyuto allows for more of the edge to make contact when sharpening on stones. Learn More

To mark its 20th anniversary, I.O. Shen has released a new knife that merges design features from the Japanese Gyuto and Bunka knives. A key feature of the blade is its clip-point. This design involves the front section of the spine being shaped with a straight cut, which repositions the tip. This lower tip position allows for detailed and precise work without needing to raise the handle to a high angle. The clip-point is designed to offer greater control for such tip work where you may be using a tip-down pull stroke, or simply doing fine work like mincing shallots. The blade features a cambered edge towards the front, for rocking motion cuts, and a generous flat section of the blade toward the heel for tap-chop and push cuts. This hybrid knife seeks to combine the versatility of two popular Japanese knife types.  The proprietary Erdon steel is tempered to a 62 Rockwell hardness and is clad in soft jacket steel of the same material. Exceptional edge retention and durability with an ebonite handle that is waterproof as well as heat and chemical resistant.  The beautiful silver scrimshaw design is constructed of steel that is welded to the tang of this blade.  It's not just painted on.  Learn More

The I.O. Shen 9 in. (230mm) Sole Knife uses I.O. Shen Triplex Steel Technology giving this knife sturdy edge retention but this knife is thin enough that it has some flex. Use this knife to break down fillets off large halibut the added weight in the handle should make this already tough task a little easier Learn More

This I.O. Shen is longer than most boning knives at 6.7 inches. It can be difficult to find Japanese steel in a Western boning knife shape. The U.S. market tends to use softer steel boning knives requiring regular honing. This is an excellent option for someone who wants better sharpness and edge retention. A unique modified VG10 steel that is tough. I am comfortable recommending this knife for breaking down fish, poultry and meats, removing silver skin, etc. If you are going to be scraping bones for "Frenching" chops and that type of task, go with a softer steel.
