When people picture classic ninja weapons, the kusarigama usually isn't the first thing that comes to mind. Most think of throwing stars or nunchucks, but the truth is, the kusarigama is one of the most unique and versatile tools in the history of ninjutsu. At first glance, it looks like a simple kama, or Japanese sickle, but the real surprise comes when you unscrew the handle and release the hidden chain. That's when it transforms into a chain kama, combining close-range cutting motions with long-range trapping and striking techniques. This Ninja Kusarigama is built with a steel blade and black-finished handle that feels solid in your hands and has just the right weight to make practice both challenging and rewarding.
The design makes it a perfect training piece for anyone serious about exploring historical ninja weapons. The blade is unsharpened, which keeps it safe for martial arts training, but the construction is sturdy enough to hold up to actual practice. The handle is about 12.5 inches long, or 17.5 inches when combined, giving you plenty of grip control whether you're using it as a standard kama or extending it into the full kusarigama configuration. Once the chain is deployed, you've got a full 24 inches of reach to experiment with wrapping, snaring, or striking. At roughly 2 pounds, it has enough heft to feel authentic without being so heavy that it's unmanageable.
Historically, the kusarigama developed as a fusion of farm tool and battlefield weapon. The kama itself was based on the sickles used to cut grass, rice, or crops. Farmers and peasants, who didn't have access to swords or spears, often turned their everyday tools into self-defense weapons. By adding a chain and an iron weight, the kama became a far more dangerous and versatile weapon, giving the user the ability to control distance. Swinging the weighted chain, a fighter could keep opponents at bay, deflect incoming attacks, or even wrap up an enemy's weapon to leave them exposed. Once the chain had created an opening, the kama side of the kusarigama could be used to deliver the decisive blow.
The kusarigama wasn't just a tool for farmers though. Samurai warriors studied it as well, and it became a specialty weapon in certain schools of martial arts. The art of kusarigamajutsu focused on mastering both the kama and the chain, teaching practitioners how to seamlessly switch between long-range and short-range fighting. Unlike weapons such as swords or spears that had straightforward attack patterns, the kusarigama relied heavily on strategy, timing, and precision. That's one of the reasons it became such a respected weapon in traditional martial arts: it was never easy to master.
Today, martial artists still train with the kusarigama as a way to preserve history and test their coordination. Because of the unique mechanics of a weapon that can shift between two forms, learning to control a kusarigama builds reflexes, balance, and creativity. In modern dojos, you might see it used for kata demonstrations or weapons practice, often alongside other traditional ninja weapons like nunchaku or bo shuriken. Even though it isn't as commonly taught as weapons like the bo staff or sai, the kusarigama continues to draw attention for its unusual design and tactical depth.
What makes this particular ninja kusarigama stand out is the way it captures that mix of history and practicality. The unsharpened blade means you can train without worrying about accidental cuts, but it's still shaped and balanced like a true kama. When you switch it into chain kama mode, the transition feels smooth thanks to the handle design that screws apart to reveal the chain. The 24-inch length is long enough to experiment with real techniques without being overly cumbersome for practice in smaller training spaces. It's a design that lets you get a feel for how this weapon was actually used in combat hundreds of years ago.
The kusarigama has always been a weapon that rewarded creativity. That's part of what makes it so fascinating to train with today. Whether you're practicing snaring techniques with the chain, working on disarming drills, or just exploring the rhythm of switching between kama strikes and chain throws, there's always something new to learn. Unlike a straightforward weapon like a sword, a kusarigama constantly challenges you to adapt.
For collectors, this ninja kama weapon also has real display value. Its black steel finish gives it a sleek, intimidating look, while the folding chain mechanism makes it stand out compared to a standard kama. It's the kind of piece that sparks curiosity when someone sees it on your wall or in your collection. People familiar with martial arts history will instantly recognize it, while those who aren't will want to know what it is and how it works.
It's worth noting that while the kusarigama is a fascinating piece of martial history, it takes time and patience to train with one safely. The weight of the chain means you need to pay attention to where it's swinging at all times, and the transition between chain techniques and kama strikes can feel awkward until you've put in enough reps. That's part of the appeal though. Mastering a kusarigama isn't easy, but once you start to get the hang of it, you realize just how much strategy is baked into its design. It forces you to think like a ninja, staying one step ahead and using creativity instead of brute force.
If you've ever wanted to explore beyond the usual martial arts weapons, the kusari-gama is a great step into something more advanced. It bridges the gap between practical farming history and battlefield ingenuity, while also giving you a training tool that sharpens your reflexes and awareness. This particular model balances durability, function, and safety, making it a solid choice for both martial artists and collectors.

What's the Difference Between a Kusarigama and a Regular Kama?
A regular kama is a simple sickle-style weapon with just the blade and handle, usually modeled after traditional farming tools. A kusarigama takes that same kama and adds a chain with a weighted end, turning it into a weapon that can be used for both close-range and long-range techniques. With a regular kama you're limited to strikes and blocks, but with a kusarigama you can swing the chain to control distance, snare weapons, or create openings before moving in with the blade.
What Martial Arts Styles Still Train With the Kusarigama Today?
While it's not the most common weapon taught in modern dojos, some schools of ninjutsu and koryu (traditional Japanese martial arts) still include kusarigamajutsu, the art of using the kusarigama. You may also see it used in weapons demonstrations, historical reenactments, and in martial arts schools that focus on preserving traditional ninja weapons. It's considered an advanced weapon, so it's usually introduced after students already have experience with simpler tools like bo staffs or nunchaku.
Is This Kusari-Gama Strong Enough for Real Training?
Yes, this ninja kusarigama is made from steel with a solid black finish, and the handle construction is built for durability. The blade is unsharpened, which makes it safer for practice, but the weight and design are authentic enough to let you train with real kusarigama techniques. The chain is also sturdy, giving you the ability to practice swinging, snaring, and trapping without worrying about it snapping under normal training use.
Can a Kusarigama Actually Disarm Another Weapon?
That's one of the main techniques the kusarigama was designed for. By swinging the chain, a martial artist can wrap it around an opponent's sword, staff, or other weapon, then yank it to break their rhythm or pull the weapon out of their hands. Once the weapon is tied up, the user can close the distance and use the kama side for a strike. Of course, this takes a lot of practice to pull off effectively, which is why the kusarigama has a reputation as a weapon that's tough to master but rewarding once you get the hang of it.
