We are pleased to offer this knife with a marbled white buffalo horn handle. Marbled white buffalo horn handles from Mizuno Tanrenjo are increasingly difficult to obtain, and we are really pleased with the beautiful white buffalo horn on this knife. 

This is a Santoku 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 santoku has superb grinds that are exceedingly smooth, with kasumi finishes. The overall grind and behind-the-edge are thin, enabling superb cutting smoothness. The Aogami blade benefits from Mizuno's outstanding heat treatment skills, ensuring superior edge retention.

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.

Your high-energy dog will love it!
Why did I wait so long to get one of these?!? I am the stereotypical throws-like-a-girl person, and my dog really needs to have an option that forces her to run far and fast. This is it. I can get that ball half a soccer field away at a minimum if I want. The ball is super bouncy, which adds an element of fun to her attempts to tame it and bring it back. Super worth the money (which wasn't much!). I've never had one of these before, so can't compare to the non-folding version. This one is easy to carry and fits in a drawer for storrage. No way you can fit it in a pocket, especially if you have a phone in one and dog treats in the other.

Great usability
I prefer this version over the non-foldable stick, as this one I can fit into my bag and carry it out easily. Great size and has a locking feature to prevent it from folding up when throwing. Highly recommend, my dogs love fetch and it is hard to chew if they get their hands on it.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.
