Cool Replicas – Part 3: The Kusanagi Grass Cutter.
Welcome to the latest entry in my “Cool Replicas” series. Today, I’ll be talking about an interesting anime sword which I like for quite a few of reasons, the most cool (imho) being that the name of this sword actually has a history in Japanese culture. Kinda like the British Excalibur… More on that later.
For now, let me introduce you to a unique shikomizue from the Naruto anime series (one of my favorites) wielded by Sasuke Uchiha, a highly talented young ninja, who later on becomes so entirely corrupted by his need for power that, much like young Anakin Skywalker, he succumbs to the dark side.
This is his signature weapon after his definitive turn to evil; The Kusanagi Grass Cutter sword.

Now if you’ve read enough of my posts, you’ll immediately spot two things that I like. Want to take a stab at guessing what they are? Sure, go right ahead. I’ll wait…
LOL yep. The astute among you might have picked up on my shikomizue reference before, and you would be right. This is very similar in design to staff sword, saya and tsuki designed to look like a single piece of wood when closed. One of my very favorite designs.
The second? OK. For those not so familiar with my taste in weapons, I’ll be nice and give you a hint:

Ok, if you didn’t pick up on it that time, you phail. The blade is the other thing I like on this. Why? BECAUSE IT’S BLACK!!!! Ha! OK. Now that we’ve gotten those little details out of the way, a little more about the sword. One of the first things I noticed was that the saya and tsuki were rectangular in cross section, which is an unusual trait.
Below you can see the detail of the black and white rectangular saya, sporting Sasuke Uchihas clan crest, (the fan in red), and more importantly, the point of the blade, an interesting hybrid between the traditional sweeping Japanese katana point style and the straight cut, sharply angled points we see on modernized/westernized ninjaken today.

Now the great thing about a weapon like this is that it’s pretty hard to mess up, replica wise. Unless the components are really dirt cheap, and it is poorly put together, it is perhaps one of the simplest designs to replicate. All in all, I like this design. Thought it could stand to be a little darker…
BUT, interestingly enough, I did find another version of this sword, a much darker version, which proved to be not so accurate, though, to their credit, they did not try to pass it off as Sasukes sword, even though it is clearly a blatant rip off:

Not so great. But now for some trivia. This particular design (in black) did not come out of nowhere. If you are one of the many who only watch anime on the cartoon channel here in the US, and don’t really know where they come from (besides from Japan, obviously) you may not realize that a great many of the popular anime series started of as Manga, or Japanese comics.
In fact most of the popular ones running now, like Naruto and Bleach, both got thier starts as Japanese comic books, and went almost immediately to TV syndication, so that the TV episodes aired almost as soon as a comic story line arc was complete. (Sometimes sooner, which often causes frequent non-storyline related filler arcs, much to my, and many others, chagrin).
Anyway the reason I brought this up is that there is a discrepancy between the Anime version and the Manga version of The Kusanagi sword. The versions we see above are actually the Manga version of the sword. The version that first appears in the Anime is a straight shikomizue (no curve) with a black saya and tsuki (no white lines), and a polished steel blade, quite similar to the black one above (except straight).
OK, so enough with the Anime trivia, on to Japanese folk history. The name of this sword is actually the name of a legendary sword in Japanese culture. The name “Kusanagi Grass Cutter” is actually a Japanese/English mix of the traditional name Kusanagi-no-Tsurugi, which literally translates to “Grass cutter sword”.
There is actually a very cool story associated with this legendary sword, I was going to go into, but I won’t bore you with it, this post has gotten too long already. However If you want more details you can click here: Kusanagi-no-Tsurugi
As you can probably imagine, my ideal Kusanagi sword would be a black saya, black tsuki shikomizue, with a straight, black, westernized tanto point blade… mmm… a totally black sword… wait… I think I’m drooling… OK I’m done. I need to get a bib for these kinds of posts…
*Edit*
An astute reader, Zharkman, was kind enough to point out that my assumption about the last, black sheathed sword being a rip off of Sasukes Kusanagi is actually false, and that it actually came from the anime D. Gray-Man. I went back and looked it up, and lo and behold, I goofed!
The last sword is actually a replica of Mugen, the signature shirasaya of the D. Gray-Man protagonist Yu Kanda. And in that capacity it is actually an excellent likeness. This is what I get for making unfounded assumptions. And for not keeping up on my anime… There are just too many of them… Dagnabbit!

Hey, Phyre! I’m considering another purchase from Trueswords, a replica of a sword from the anime “One Piece”. I wonder, would you mind looking at it and giving your professional opinion?

Indeed! As a matter of fact, this weapon just so happens to be one of those in my list of “Replicas that Don’t Suck”
So you should see a post on it relatively soon…
Sweet- I look forward to reading it!
Have at it!
Nice info.. very well explained.
I try…
…. pet peeve, A SHIRA-SAYA IS A STORAGE DEVICE NOT A FUCTIONAL DESIGN GAH!
Aw, come on take it easy, Mozz,
Yes, Shirasaya were originally intended for storage, but they look so good… I really can’t blame anyone for co-opting the design for daily use, even though they introduce some rather glaring practical use problems.
They are just so clean and simple in comparison to traditional saya and tsuka design. And, of course, they store well by design. Simpler too. No Tsukamaki. And much easier to conceal. It’s just convenient on soo many levels…
convinient but im a traditionalist phyre!
Glad I saw this on the grapevine, I have only been a fan of the site for a month or two and didn’t see this post, but I have this sword! Well I have Sasuke’s Grass Cutter, so if you’d like any pictures or any more detail about it then you already have please feel free to ask!
@Mozza
Well, certainly nothing wrong with being a traditionalist. My philosophy is more along the lines of adapting old designs to new uses…
@TheHat
Thanks!
exactly adapting a proven working design to accomadate modern needs is what its all bout brother!
Okay, the black blade with the white in the middle Just a comment, but that’s a blade from a different anime.
D. Gray Man’s Yuu Kanda’s blade. Look it up. Just an update =)
btw it’s name is Mugen
