1. Rambo knives: every knife from First Blood to Last Blood
"The Rambo knife" is really several knives. John Rambo carries a different blade in almost every film, and each one changed what people picture when they think of a survival knife. Here is what he carries in each film.
First Blood (1982): the original Rambo knife
The First Blood knife was made by Arkansas knifemaker Jimmy Lile. It is a hollow-handle survival knife with a saw-backed clip-point blade and a compass in the pommel, with survival gear stored inside the handle. It started the survival-knife craze of the 1980s, and original Lile knives are now serious collector's items.
Our version: the Rambo First Blood replica knife has a 10-inch stainless steel blade and a cord-wrapped handle (15 inches overall).
Rambo: First Blood Part II (1985)
Lile made a larger knife for the sequel. It differs from the first in its blade finish, the shape of the blade and saw teeth, the guard and the buttcap. It is often called the "Mission" knife.
Rambo III (1988): the Gil Hibben Bowie
For Rambo III, the job went to Gil Hibben. His Rambo III knife is a large, heavy Bowie with an oblong hole cut through the blade and a dark wooden handle, and it is the version most fans picture today when they search for a "Rambo knife replica".
Our versions: the Rambo III replica Bowie knife (12-inch high-carbon steel blade, wooden handle, leather sheath), the 18-inch Rambo III Bowie knife and the Rambo III movie replica knife.
Rambo (2008): the Rambo IV machete-knife
Hibben also made the blade for the fourth film, and it looks nothing like the earlier knives. It is a crude, hammer-marked, machete-like blade with a handle wrapped in black tape, made to look as if Rambo forged it himself.
Our version: the Rambo IV black machete replica has a full-tang 1095 carbon steel blade and a cord-wrapped handle.
Rambo: Last Blood (2019): the HeartStopper
In Last Blood, Rambo uses a large Bowie-style knife known as the HeartStopper, which brings the series back to a classic fighting-knife shape.
Our versions: the Rambo V HeartStopper replica (10.5-inch stainless steel blade, 16 inches overall) and the Rambo V replica Bowie knife.
2. Thorfinn's daggers (Vinland Saga)
What weapon does Thorfinn use? In Vinland Saga, Thorfinn fights with short daggers rather than the swords and axes most Vikings carry. He starts with a single dagger as a boy who is set on revenge after his father Thors is killed. He later fights with two daggers while serving in Askeladd's warband.
Why daggers? Thorfinn is small and fast, so he relies on speed, agility and precise strikes at weak points rather than strength. The paired Thorfinn daggers are one of the most recognisable weapons in anime. They also matter to his story: after Askeladd dies, he gives up killing and leaves the blades behind.
Our version: the Vinland Saga Thorfinn replica daggers are our best-reviewed anime piece, rated 4.9 out of 5 from 13 customer reviews. Each dagger is handmade with:
- a full-tang D2 steel blade (about 8 inches on the main dagger, 13 inches overall)
- a micarta handle wrapped in leather
Each pair suits cosplay, display or an anime collection.
3. The Catspaw dagger (Game of Thrones)
What is the Catspaw dagger? It is a Valyrian steel dagger with a dragonbone hilt. It takes its name from season one, when a hired killer (a "catspaw") uses it to try to kill the unconscious Bran Stark. Catelyn Stark stops the attack and takes the dagger to King's Landing, setting off the conflict between the Starks and the Lannisters.
Who owned it? Littlefinger claimed he lost it to Tyrion in a bet, which was a lie, and he later took it back. In season seven he gave it to Bran, who passed it to Arya Stark. Arya used it to kill Littlefinger. In the Battle of Winterfell she stabbed the Night King with it, destroying the army of the dead. That moment made the Catspaw dagger, also called Arya Stark's dagger, one of the most searched-for weapons in fantasy TV.
Our version: the Catspaw dagger replica has a Damascus steel blade, whose swirling pattern is the closest real-world match to Valyrian steel, and a dragonbone-style handle. It is rated 5 out of 5 by customers.
Arya's other famous blade is Needle, the slim sword Jon Snow gives her. Our Game of Thrones Needle sword replica comes with a wall mount, which makes a matching pair with the Catspaw dagger.
4. The Dune Crysknife explained
What is the Crysknife in Dune? The Crysknife is the sacred blade of the Fremen, the desert people of Arrakis. It is made from the tooth of a dead sandworm, which gives it its milky-white, slightly curved blade.
How long is a Crysknife? In Frank Herbert's novel, the blade is about 20 centimetres (roughly 8 inches). Film versions are often drawn larger.
Fixed and unfixed Crysknives. An "unfixed" Crysknife breaks down when it is away from the electrical field of a human body. A "fixed" one has been treated so it lasts.
Fremen traditions. A Crysknife is given to young Fremen when they come of age. Once it is unsheathed, it must draw blood. Paul Atreides carries one throughout the story and uses it in his final duel with Feyd-Rautha.
Our version: the Paul Atreides Crysknife replica is a Dune Crysknife replica with:
- a D2 steel blade, about 16 inches, matching the film's larger look
- a steel-and-wood handle
- a leather sheath
To complete the duel, we also make the Dune Part Two Feyd-Rautha knives.
5. Demon Slayer swords: Tengen Uzui's Nichirin blades
What is a Nichirin sword? In Demon Slayer: Kimetsu no Yaiba, every Demon Slayer carries a Nichirin sword forged from special ore that can kill demons. Most are katana-style, but the Hashira, the elite swordsmen, often carry blades as unusual as they are.
Tengen Uzui's swords are the most extravagant Demon Slayer swords in the series. The Sound Hashira wields two huge cleaver-like Nichirin blades joined by a chain, which he swings in combination during the Entertainment District arc. Their size and the chain between them make them a favourite for cosplay and display.
Our version: the Tengen Uzui double sword is a handmade Tengen Uzui Nichirin sword set with two blades, rated 5 out of 5. It suits conventions, photoshoots or a game-room wall.
How to choose a replica knife or sword
Whether you are buying for yourself or looking for gifts for anime fans and movie lovers, these are the points that separate a good replica from a cheap one:
- Real steel, not zinc alloy or plastic. Cheap replica swords and knives are often cast metal that bends or snaps. Ours are handmade from D2 steel, high-carbon steel, Damascus steel or stainless steel, and the steel is named on every product page.
- Full-tang construction. The blade should run through the handle. This is what makes a replica feel solid and balanced in the hand.
- Screen accuracy. The blade shape, guard and handle wrap should match the film or anime closely enough that fans recognise it straight away.
- A sheath or mount. A leather sheath or wall mount protects the blade and makes the piece ready to display or gift.
- Care. High-carbon and Damascus blades need a light coat of oil after handling so they don't rust. D2 steel is more rust-resistant but still benefits from the same care.
- Local laws. These are real steel blades, so check the rules where you live before ordering. Our knife safety and legal notice explains more.
