I.O. Shen Knives

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

The I.O. Shen Chinese Cleaver is superior in multiple ways. Coming from Nirey's knife factory in Taiwan made of proprietary Erdon steel with a hardness of 62. This is a hard steel that will not lose an edge easily, Nirey's unique Triplex knife technology allows for a uniquely thin layer of jacket steel this protects the high quality Erdon steel from chipping and damage and Triplex technology means the buyer is getting more of the premium cutting steel almost two credit cards thick, more than the competition.

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.

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

A Michelin-Standard Hybrid That Redefines Precision Slicing When two-Michelin-star chef Daniel Clifford designed the I.O.Shen MSH Ryoba, he wasn't looking for another standard carver. He needed a tool that could handle the intricate work of a 12-hour service—slicing delicate proteins while possessing the structural integrity to clear small bones and cartilage without damaging the primary edge. The result is the MG4200, an 8.25-inch masterpiece that bridges the gap between Japanese surgical sharpness and Western heavy-duty utility. At the heart of this blade is I.O.Shen's signature Triplex Steel Technology. Unlike cheaper stamped blades or even traditional single-alloy forged knives, Triplex features a high-carbon Erdon 6000 core (Rockwell 62) sandwiched between two layers of softer stainless steel. This construction creates a 'self-honing' effect as the outer layers wear, while the core maintains a razor-sharp 15-degree edge through hundreds of cuts. Whether you are portioning 40 lbs of brisket or filleting a delicate sea bass, the edge remains consistent. What truly distinguishes the Ryoba is its 'toothed' heel. Inspired by the Japanese Ryoba saw, this serrated section allows you to initiate cuts through tough skin or small bones that would normally dull a standard carving edge. It gives you the confidence to use the front 80% of the blade for flawless, clean-slice presentation, while relying on the heel for the heavy lifting. The medium-sized handle and balanced weight distribution make it a favorite for chefs who find traditional carvers too cumbersome for fast-paced line work. Learn More

The I.O. Shen two piece knife set features the I.O. Shen 6.3 in. (160mm) Santoku and 4.1 in. (104mm) Oriental Parer. Both knives use I.O. Shen Triplex technology giving these knives both great edge retention and toughness to excel in a professional kitchen. Learn More

The I.O. Shen 6.5 in (165mm) Nakiri is a standout vegetable prepping knife. The large, weighted handle allows you to chop and mince for hours with comfort and the Triplex Steel blend has 62 Rockwell hardness that tapers down to a razor edge. 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 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
