Hand-Forged WWII-Era Chirra Khukuri

Chirra is the Nepali word for a fullered blade, and in practice it is used as a family name for khukuris cut with grooves along the length of the blade. The counting matters, because the terms are specific: a single groove near the spine is usually called angkhola, which translates roughly as body groove; two grooves are dui chirra; three are tin chirra. Beyond three is rare and mostly a display of skill. The distinction is not decorative. Each groove removes a further slice of weight from the blade and adds a further day of hand grinding, so the pattern you choose is a decision about how the knife will feel and what it will cost, not about how it looks. If you are comparing khukuris from any seller, counting the grooves tells you a good deal about what you are being offered.

Because taking the same weight out in several shallow cuts leaves a stronger blade than taking it out in one deep one. A fuller works by removing steel from the middle of the blade's thickness, where it contributes least to stiffness. But a single deep groove concentrates that removal in one line, thinning the blade dramatically at that point and creating what an engineer would call a stress riser, a place where a bend will naturally start. Spreading the same material loss across two or three shallower grooves keeps more thickness at any given point, distributes the transition across several gentler curves, and leaves ribs of full-thickness steel between them which stiffen the blade in the way corrugation stiffens a sheet. That is why the multi-fullered patterns have a reputation among kamis for resilience rather than merely for lightness. Our deep-fullered kukri page sets out the underlying structural argument if you want it in more detail.

No, and we would rather say so here than let a collector tell you. This is built to the proportions of the period, which is why we call it a WWII-era pattern rather than a service replica. The 13 inch blade is right at the issue length and the plain riveted scabbard is far closer to military than a decorated one. What is not issue is the construction. The official patterns from 1903 onward closed a full rat-tail tang with a circular nut recessed into the butt, and used steel fittings throughout. This khukuri has a riveted full tang with visible pins and a brass bolster, both of which are traditional Nepali civilian work. Neither is a compromise; a riveted full tang is arguably the more robust arrangement. It simply is not what a quartermaster issued. Our WWI-era pattern khukuri page sets out the four diagnostics for telling issue from civilian, and they apply here too.

Panawal is the Nepali term for a khukuri built with a full-width, full-length tang and the handle scales riveted through it, which is what this one has: you can see the pins in the grip and the steel of the tang along its edge. It is worth knowing because Nepali khukuris are made three quite different ways. The traditional village construction is a partial tang set into a drilled handle and fixed with laha, a resin adhesive, which is strong and completely invisible from outside. The official military patterns used a full rat-tail tang drawn up under a nut sunk into the butt. Panawal is the third way and the most robust of the three for hard use, because there is no adhesive to fail and no single threaded point carrying the load, just steel and rivets along the whole length. The trade is weight and the fact that the tang is exposed to weather along its edges, which is one more place to keep oiled.

Yes, though not as an issue pattern. The chirra was well established in Nepal long before the British standardised anything, and it gained wider military use in the interwar years, when soldiers who wanted a lighter blade than the issue one could have a fullered khukuri made at home. That is the honest position: a chirra khukuri of this period is far more likely to have been a private purchase or a family piece carried alongside issue kit than something drawn from stores. Given that a great many Gurkhas did carry khukuris from home throughout both wars, a fullered blade in the hands of a serving soldier is entirely plausible for the period. It just would not have had a broad arrow on it.

Two pages, two different periods and two different builds. Our WWI-era pattern khukuri is the larger of the pair at 15 inches, with a single spine fuller, a decorated cast chape and older, longer proportions that sit closer to the nineteenth century heritage sizes. This one is 13 inches, which is the service length of the later period, with chirra fullering, panawal riveted construction and a plain riveted scabbard much nearer to military dress. Take the 15 inch if you want presence and the older silhouette; take this one if you want something closer to service proportions and a blade you will actually carry and swing. For documented service reproductions rather than period patterns, our historical replica collection is the right place.

It takes weight off the blade without taking it off the belly, which is the only place a khukuri actually needs it. At 630 grams bare for a 13 inch blade, this sits in the middle of our khukuri range rather than at the heavy end, and the difference shows up in how long you can work with it rather than in how hard it hits. A plain blade of the same dimensions is noticeably heavier in the hand and will out-chop it on any single stroke; this one will still be swinging comfortably when the plain blade has tired your forearm. That is the trade, and which side of it you want depends entirely on whether you are clearing a path or splitting a log. If you are unsure, the plain build costs less and hits harder, and we would rather tell you that than sell you the more expensive option by default.

Yes, both, in fitted pockets on the scabbard. The karda is the small sharpened utility knife for the jobs a 13 inch blade cannot manage, and the chakmak is a burnisher for truing the khukuri's edge between sharpenings and for striking sparks from flint. The chakmak is meant to be blunt and that is not a fault; our kukri with karda and chakmak page explains what both tools do and how to use the chakmak properly, and it is worth reading if you have not used a set before.

A working knife, and the fullering is the evidence. Nobody cuts grooves into a curved blade by hand for decoration alone; it takes days, it is the most unforgiving grinding a kami does, and the reason the pattern survives is that it makes a heavy blade usable for longer. This one will chop, split, clear and do everything a khukuri is for. The polished finish is the only thing on it built for looking at rather than using, and if the knife is going into a pack rather than onto a wall, the satin or dark forge finish costs the same and will look better after a season. What it will not do is fine work, which is what the karda is in the scabbard for.

We cannot answer that for you and you should be careful of any seller who claims they can. At 13 inches this blade is above the everyday carry allowance in most jurisdictions, and the khukuri's distinctive shape means it is sometimes named or recognised specifically where a plain knife of the same size would pass without comment. Rules for owning one at home, carrying one while working outdoors and importing one across a border are frequently three separate matters with three different answers. Check all three for your own address before ordering. If length is the obstacle, a 10 or 11 inch build costs no more.

5160 high-carbon spring steel, forged down from leaf spring in the Nepali tradition, which is the same stock and the same method our smiths use for khukuris that go to working households in Nepal. It is oil-quenched and then tempered back. On a chopping blade toughness matters more than outright hardness, because the edge will meet things it was not aiming at, and a blade that rolls and can be trued back is far more use than one that chips. It is not stainless: it will take a patina with use and it will rust if left wet.

Close, but not identical, and on a chirra rather less so than on a plain blade. The curve is drawn out by eye and hammered rather than cut from a template, so the sweep of the belly varies from piece to piece. The fullers are then ground by hand to follow that individual curve, which means their exact length, depth and where they run out toward the point are decided at the grinding wheel rather than set by a jig. Two chirra khukuris from the same bench on the same day will differ visibly. Rosewood varies board to board, and the scabbard core is shaped to the individual blade. What does not vary is the specification: length, steel, construction, heat treatment and sharpness are held to the same standard on every piece.
