Now THIS is a REAL Ninja Sword: originally custom designed for the Bujinkan Federation and now made available to members of the general public...

Unlike in Hollywood, where the Ninja walk around in broad daylight doing back flips dressed in their 'black pajamas', the real Japanese Shinobi would be undistinguishable from every other person around them - until it came time to act that is! In this time honored tradition, the Oniyuri Katana makes the perfect Shinobi weapon: on the outside, it looks like any other ordinary Katana - but the shorter blade gives it an unfair advantage on the draw, and if need be can be followed by a rapid succession of swift, close in and unfamiliar attacks until the opponent is quickly overwhelmed and neutralized before they have a chance to work out what is going on.

Fast handling (especially the 'bo-hi' fullered option), frighteningly sharp and forged from extra tough 9260 Spring Steel that Cheness has become famous for, the Oniyuri makes an eminently durable and practical cutter and is unique to Cheness Cutlery.

WARNING: Due to the appleseed sharpness of the blade, it is strongly NOT recommended to practice quick drawing the blade unless under the supervision of an appropriately qualified Ninjutsu instructor. Blades with this geometry may appear to be dull but will cause a devastating slice when set in motion.

Cheness Cutlery Swords are designed by Martial Artists for Martial Artists. Their goal is and always has been to simply offer an affordable entry level practice sword to beginners in iaido and iaijutsu and when first released in 2005 truly revolutionized the sword market for until that time, there were few to no entry level Katana.

Cheness swords were never meant to be collectors pieces, display pieces, or art sword quality. There are numerous other manufacturers and individual smiths in the industry that serve those needs (click here for our full selection of Japanese swords). The reason being the same as with all other hobbies, refinement will come with a price.

Because of this, certain shortcuts must be taken in the manufacturing process and are NOT considered to be defects. Because of this, we will not accept returns on any swords that have the following features:

  • The polish of each sword is a working polish known as a 'Tameshigiri' polish and is somewhere between 400 to 600 grit. As they are handmade and subject to extensive handling, they do get scuff marks and minor stains on the blade and components.
  • Each blade is hand hammered, shaped to the eye, and then tempered and quenched. This process causes all types of steel to contract, twist and warp to some degree -with 9260 being one of the hardest steels to keep straight - so you should not expect the blade to be perfectly straight like a lazer. Even if slightly off center or imperfect, it will still cut perform for Tameshigiri and you can be confident in the tempering.
  • The blades have considerable hira-niku (meat) on them for heavy cutting and will generally feel somewhat dull to the causal observer. It will not slice paper or shave hair off your arm. It WILL cut tatami mats or bamboo or other targets that were traditionally used to simulate human limbs. With only a little work however, it is quite possible to sharpen it to any degree desired.
  • The cotton ito wrap is tight enough for use, but is not going to be as tight as silk or leather. Habaki, Seppa, Fuchigashira, etc are free floating and pinched into place by friction forces like a traditional Katana, but some minor adjustments may be necessary out of the box.
  • Mekugi pegs are angled by design to create a wedge and optimize the double mekugi configuration. The bottom peg is made of brass, the top, bamboo which results in an overall stronger design and was recommended by a senior Japanese JSA Sensei.

Please read this article about Cheness Cutlery to ensure you completely understand what to expect before you purchase.

In short, you should not expect an art sword or something perfect out of the box. You will almost certainly need to make some adjustments or even a complete DIY overhaul (we have many free tutorials on how to do this right here on the main SBG website). But for those of you who don't mind a rough and ready sword, or who wish to take it to a higher level, you will find these blades to be extremely long lasting, tough and worth every penny.

In summary, Cheness puts it like this:

The issues can all be addressed by the end user if they so choose. After receiving the sword, you can adjust the components, add a high-grit diamond paste polish, deburr the blade to slice paper, polish the components, etc. to make it as refined as you choose. However, these are not the features we strive for and should not be expected of the sword out of the box. If a highly refined sword is what you are after, you will either need to be prepared to perform these refinements yourself or should purchase a higher end sword from a different manufacturer.

Please note, as to be expected issues like cracked blades, broken handles, etc are of course subject to our standard warranties and return policies.

This sword feels very solid in hand... As if it were part of your arm with a lot of presence felt in the bicept just behind the elbow it is this feeling that allows you to switch grips and compete with a standard katana.......your wrist and forearm are allowed fine control ..with heavy practice it will build powerful upper arms connected through the elbow to the upper shoulders shoulder blades and latts you feel the potential cutting power through every swing like a well balanced light battle axe... I have no complaints about its will preform to high expectations

great black sword box left something to be desired. It was dented in travel and I wouldn't want to store it in a moving truck near anything heavy.

My only real issue is the fittings...I was expecting a matainace kit but it appears that is no longer offered with purchase...the habaki was ground off on one side to low where the sword blades spine rests in the saya and the blade corner protrudes out and scraps the mouth inside the scabbard taking material every time the sword is removed until it has nothing left to make contact with.

COSMETICS: this is not a decorated blade dull black cotton ito...let may i say though it was impressively solid I don't feel it would of loosened i have taken it off to thin the tsuka for a tighter grip and it was a top of the line profetional wrap....difficult to move from the place it was in...the blade is has a dull polish ...I prefer a slight mirror polish..I will stone sharpen the edge a lil finer it cuts but it can be made to cut finer...very good shape I love the kissaki and the point on the tip....I may change the tsuba for something smaller and heavyer ...I would like to see how it handles with a low profile tanto inspired tsuba...i prefer the look but I bought this for function

OVERALL: I would call these a supreme functional blade..versatile for indoor and outdoor use...handles as well as a full sized katana as advertized...i have a 30 inch blade that feels slightly off balace compared to the low grip on the oniyuri...leaves a bit of desire for cosmetics...and the habaki is a bit aggrivating but I don't feel cheated out of my money and I love this sword ..I would reccomend it to anyone looking to build themself around there sword and learn to use a unuiqe weapons and hone control fluid adaptation speed and power
