We are pleased to offer this knife with a marble blonde buffalo horn handle. Marble blonde buffalo horn handles from Mizuno Tanrenjo are increasingly difficult to obtain, and we are really pleased with the beautiful marble blonde buffalo horn on this knife. Photos shown are of the actual knife.

This is an Kama-Usuba knife from Mizuno Tanrenjo's "Akitada Hontanren" range - a relatively more affordable line compared to their Honyaki range. Hand-forged by 5th generation Mizuno master blacksmith Jun Mizuno, and sharpened by extremely experienced sharpener Tsutomu Minamiura, this usuba knife has superb grinds that are exceedingly smooth, with kasumi finishes and excellent polish. The Aogami blade benefits from Mizuno's outstanding heat treatment skills, ensuring superior edge retention. With the hardness of the steel, the sharpener was able to create an exceedingly thin edge, ensuring outstanding cutting performance. Mizuno has paired this blade with a magnolia handle featuring a beautiful white/blonde buffalo horn kuchiwa.

About Mizuno Tanrenjo 水野鍛錬所 / Minamoto Akitada 源昭忠

Established in 1872, the Mizuno Tanrenjo workshop is one of the most prestigious blacksmith workshops in Japan. Five generations of Mizuno blacksmiths have worked on projects of cultural significance and won accolades for their craftsmanship. The works of 2nd generation blacksmith Masanori Mizuno still hangs on top of the pagoda at Japan's first UNESCO site, and the 3rd generation Akiharu Mizuno - a portage of Japan's national treasure blacksmith Teiichi Tsukiyama - has won a prestigious award for his honyaki yanagiba. The Mizuno family workshop has received two royal visits by Prince Mikasa of Japan, who is personally a fan of their craftsmanship. Today Mizuno Tanrenjo is led by 5th generation master blacksmith - Jun Mizuno (a.k.a. Noritada Mizuno) whose superior craftsmanship and extraordinary honyaki works have been recognized by two of Japan’s top Ichinomiyas (shrines) which have commissioned his katanas to become the shrines’ permanent collections.

Care:

Aogami #2 (Blue #2) steel is a premium Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.

Good for a while
Pattern Name: Tug Rag
My GSD puppy, at 6 months made shredded leather out of this in a matter of weeks. Initially it was fine but if you spend more than an hour or two playing with your dog, chances are this toy will begin to tear.

Crazy how much our dog loved this
Pattern Name: Tug Rag
It is crazy how much our baby loved this thing. Has held up decently except she chewed off the handle like a goober. Fun to play tug of war with. Soft and safe for teeth. She loves carrying it from room to room, nice and light.

Recommend
Pattern Name: Tug Rag
This is the best toy for puppy teeth. If you want to play with your pup you can hold with your hands & it protects your fingers. Our pup does prefer this toy to others & I think it is because the leather is thick.
