Hand-Forged Fantasy Kunai Dagger

Digging, prying and gouging. The kunai was a mason's and gardener's tool in Japan, and surviving examples look very little like the sharp black knives the word now brings to mind: they are thick, heavy, roughly finished, blunt along the edges, and made in a leaf or trowel shape with a ring at the end of the tang. The ring took a cord, so the tool could be hung from a belt, tied to a longer handle to extend reach, or lashed to something. The work it did was practical — opening holes in plaster and daub walls, levering out stones, digging, chiselling. There is a reasonable case that it was also used by people who needed to get through a wall quietly, which is where the association with covert work comes from, and a tool is a useful thing to be caught carrying precisely because it is a tool. But it was not a fighting knife, it was not sharpened like one, and the throwing weapon is a twentieth-century invention that arrived through fiction, film and games rather than through any historical source.

Please do not, and we will not sell it as a throwing knife. Three reasons, all practical. Purpose-built throwing knives are made from softer, thicker stock with rounded or blunt edges and no fine point, precisely because they are expected to hit steel-hard targets end-on, tumble, bounce and land on stone; a properly hardened cutting blade with a fine point chips and snaps under exactly that treatment. Second, this one has a rosewood-scaled hilt: throwing loosens pinned scales over time no matter how well fitted, and a handle that works loose on a thrown knife is dangerous to whoever picks it up. Third, the ring makes it worse rather than better, because it catches on release and sends the knife off-axis. If you want something to throw, buy a set made for it, which will cost less and last far longer. This is a knife with a ring on it.

Because it is the modern idea of the object rather than the historical one, and we would rather say so in the title than argue about it in the small print. What people picture when they hear kunai is a sharpened, slim, blackened blade with a ring, thrown in handfuls — and that picture comes from manga, anime, games and film, not from any Japanese tool chest. We have built that picture properly: forged carbon steel, full tang, heat treated, sharpened, with a ring big enough to be real. What we have not done is pretend it is a historical reproduction. Our catalogue has pages where we reconstruct a documented weapon and pages where we build a modern design well, and the difference between the two is the most useful thing we can tell you. This is the second kind. The first kind is the tool-form kunai in the build options above.

Because the proportions come from the tool, and it is one of the few things about this design that is genuinely period. On a kunai the tang is long, often close to the length of the blade, because the tool was meant to be gripped in different places depending on the job, choked right up for careful gouging or held at the end for leverage when levering. Ours keeps that: 6 inches of grip on a 10 inch blade, where a knife of this size would normally give you four. The result handles unlike anything else in the catalogue — it feels closer to a small prybar than a dagger, which is exactly right. If you want it to feel like a knife instead, order a shorter grip and we will rebalance it, though you will lose the silhouette that makes the shape recognisable.

On the original, a cord. The ring is not a pommel in the sword sense and it was not there for the hand; it existed so the tool could be tied to something — a belt, a wrist, a pole to extend its reach, a rope to lower it or retrieve it. On this build it does three useful things. It takes a lanyard, which is genuinely worth having on a knife with a slim grip. It gives you somewhere to hang the piece for display, which matters because a kunai looks wrong lying flat and right hanging point-down. And it takes a finger, which changes how the knife handles in a reverse grip. Ours is forged and finished to a size that will actually accept a cord or a finger, because a token ring too small to thread is one of the giveaways on cheap versions of this design.

For this design, probably. A kunai alone on a wall reads as an odd single object; two or three read as a set and look like what they are meant to be. That is true in the fiction the shape comes from and it is true visually. Ordering them together also gets you pieces that genuinely match: forged in one batch from the same bar, the same grind, scales cut from the same board so the grain and colour agree, and rings shaped to the same size by the same hand. Order singly across months and they will not match, because hand forging varies and rosewood varies more. A set costs less per piece than the same number bought separately, and it is the most common request we get on this design. Tell us the number at the start rather than adding to a set later.

5160 high-carbon spring steel, brought to temperature in the forge, quenched in oil and tempered back so the edge is hard while the body stays springy. That is the same steel and the same treatment we use on our working knives, which is worth saying because most of what is sold in this shape is stamped stainless sheet with a cast ring, unhardened, and functionally decoration. It is not stainless, deliberately, for the same reason as every other blade we make: the stainless grades that genuinely resist rust give up toughness, and we would rather sell a knife that needs oiling than one that will not hold an edge.

Yes. The tang is the full width and shape of the grip with rosewood scales pinned through it, and the ring is forged as part of the same piece of steel rather than welded or fitted on afterwards. That matters more on this design than on most, because the ring invites people to hang it, swing it from a cord or pull on it, and a ring that is a separate component attached to a narrow tang is the obvious failure point. Almost nothing else in this category is built this way. If you see a kunai where the ring is a different colour or finish to the tang, it was made separately and joined.

Sharp and ready, with the edges put on a stone by hand at the forge. If you would prefer it shipped blunt — for display, for costume or convention use, for a gift, or because of the rules where you live — say so in the order comments and we will send it unsharpened at no extra cost and rebate the point as well. Many conventions require exactly that, and on a piece bought largely for how it looks it costs you nothing.

An angular ricasso, cut with flats where the blade meets the tang. It gives the eye a clean transition between a wide blade and a slim grip instead of the abrupt step you get on a stamped version, and it is a place your thumb can sit if you choke up on the blade for close work. On the historical tool this area is usually a plain thick shoulder with no shaping at all, so the faceting here is ours rather than period — a detail that makes the piece look considered, which is the point of it. It is also, incidentally, one of the hardest parts to keep free of rust, since the angles collect moisture that a cloth wipes straight over.

Yes, and it is more interesting than most people expect. A tool-form kunai is thicker through the blade, blunt or nearly blunt along the edges, rougher in finish with the forge marks left visible, and carries a heavier ring. It is a genuinely useful object — it will dig, lever, gouge and pry, and it does those jobs better than any knife because it is not trying to be one. It also looks nothing like what people expect, which is exactly why collectors of Japanese tools want them. Tell us in the order comments or through the custom forge page. We would suggest ordering one alongside the fantasy version rather than instead of it, because the pair together tells the whole story of how a mason's tool became a fictional weapon.

In our own workshop in Tokha-3 on the northern edge of Kathmandu, Nepal, by around ten smiths, most from families that have forged blades for generations. Everest Forge has operated since 2010, and we forge, grind, heat treat, fit the scales and cut the leather in the same building. A Japanese-derived shape made in Nepal deserves the same word we give our bowie, our seax and our kopis: this is not our own tradition and we do not pretend it is. What our smiths bring is the forging, and forging the ring as part of the tang rather than adding it afterwards is the part of this design that actually takes skill.
