Ryusen Hamono

Ryusen Hamono is a maker working out of Echizen City, Fukui Prefecture, Japan. They fully embrace the tradition of the region and take great pride in every step of the knife making process. They produce knives with both modern and traditional techniques, creating excellent finishes that are beautiful and comfortable to hold. Each blade is hand sharpened to be impeccable straight out of the box. Winners of numerous design awards and supporters of the Japanese national team at the Bocuse D'or, their knives are popular with professional chefs and home cooks alike.

Ryusen Hamono works primarily with SG2/R2, a high powder stainless steel that is very hard and grinds super thin behind the edge. The blades generally have a shorter blade height, which makes them great for precise slicing tasks. Their profiles vary quite a bit, from aggressive sweeping k-tips to more traditional yet modern gyuto shapes. The blades are very consistent, as they employ both modern and traditional techniques, each blade is hand sharpened and impeccably sharp out of the box. Every handle has a unique pattern, particularly the Blazen line, which has a distinctly comfortable taper, compared to the Tanganryu line, which is a hybrid western micarta handle, also with a smooth finish.

From the Ryusen Hamono Website...

"— Massive presence and reliable sharpness —
The Super Gold II, made by a top-level manufacturing method achieved by the dramatic improvement of steelmaking technology, is adopted for the blade. This ultra-high-end cutting steel material—excellent in terms of the four major properties of hardness, tenacity, wear resistance and corrosion resistance—was forged using the traditional Echizen Uchihamono forging technique. The blade has an edge where ripple patterns as beautiful as those of Japanese swords stand out, and long-lasting sharpness and durability achieved by buffing it to the utmost limit. The Blazen Ryu is a series for professional use finished by artisans with painstaking attention to detail.

The Knife

The Blazen line from Ryusen Hamono have the same level of fit and finish you can expect on all of their knives, top notch! Where this line differentiates itself from their other lines is the incredibly thin grinds on these knives. While they lean more towards the delicate side of things, they put performance first and are some of the best cutters in the shop. With a classic Ryusen contoured handle, R2 (SG2) stainless steel, and a gentle tsuchime to the hira of the blades, these understated knives are some of our favorites!

The Bunka is a mid sized prep machine that is as versatile as it is cool! The K-tip or reverse tanto brings the tip closer to the board making them great for intricate tip work and usually means a flatter profile which is great for chopping or push cutting and makes it a more viable (though still limited by length) slicer. These knives are great for home cooks uncomfortable with larger knives or smaller workspaces, and are great for professionals looking for something a little more compact to reduce the fatigue of longer use sessions for busy prep days!

Knife Care (Stainless Steel)

Although this knife is made from stainless steel we do still encourage our customers to keep their knives as dry and clean as possible.
NO DISHWASHER - the high heat will ruin the wooden handle.
Wash and dry by hand using regular dish soap and warm water using a none abrasive sponge or cloth.
Ensure the knife is dry before being put away for storage and ensure the edge of the knife is protected to avoid any unnecessary dulling.
Avoid Bones, Frozen foods, nuts and hard candies or anything other than fruits, vegetables and proteins.

CARE INSTRUCTIONS

Follow these care recommendations for your Japanese knives to protect the edge and keep them sharp as long as possible:

Do not put them in the dishwasher or soak them in water, as this may ruin the wooden handle and rust the blade.
Wash with soapy water and wipe dry after each use, especially after handling acidic ingredients, to minimize the risk of rusting.
Don’t cut through anything you wouldn’t bite through, like frozen foods, hard candies, or bones, as this may chip or damage the knife.
Don't torque the blade, as this may chip the knife. Use it in a forward and back, up and down motion without twisting.
Don’t scrape the cutting board with your knife, as this will cause it to dull quickly and ruin your edge.
Use an end grain wooden cutting board or hi-soft rubberized cutting board if you can to protect your edge. Glass, bamboo, and granite are terrible materials for cutting boards, and plastic is only slightly better.

KNIFE SHAPE

THE BUNKA

The Bunka is a mid-sized, all-purpose knife that is compact, nimble, and handles many tasks. It's a touch shorter than the Gyuto and Kiritsuke, making it easier to wield and less intimidating to use. The "reverse tanto" or "K-tip" gives the user more travel for their guide finger toward the tip of the knife, which is super handy for tasks that require precise tip work, like brunoise shallot or garlic. It's great at slicing smaller proteins and flying through any mid-sized vegetable.

STEEL TYPE

R2 (SG2)

R2 and SG2 are technically different steel types, but are so similar we and many other retailers lump them into the same category. They are what’s known as a “quick powdered” stainless tool steel with incredible edge retention and corrosion resistance. Their one drawback is that their hardness can make them difficult to sharpen. It is not a steel we would recommend for those planning to thin and polish the bevels of their knives unless they are equipped with the proper tools (you will need a low grit stone in the #200 grit range).

Chemical Composition:
C 1.25-1.45% | Cr 14.0-16.0% | Mo 2.3-3.3% | V 1.8-2.2%

COMPOSITION

STAINLESS STEEL

LOW MAINTENANCE

Stainless steel Japanese knives are made in a process called “Sanmai” or “Forge welding” where two softer layers of stainless steel are laminated around a harder core layer of stainless steel. All three of these layers are rust resistant and therefore are not susceptible to rust or discoloration. The softer outer layers of steel are used to make the knife more durable and flexible while the harder core layer is used to provide better edge retention to the blade.
