Hand-Forged Mandeville Dagger, Cross Guard

Geoffrey de Mandeville, 1st Earl of Essex, was one of the more notorious figures of the English civil war of the 1140s known as the Anarchy. He sacked Ramsey Abbey, was excommunicated for it, and when he died in 1144 he could not be buried in consecrated ground, so his corpse was sealed in lead and hung from a tree until the Templars interred him in Temple Church in London, where his effigy still lies among the knights. This is not his dagger and it is not a reproduction of his arms. A weapon of his actual era would look quite different: a brazil-nut pommel, a broad blade of near-even width, and a plain straight cross. The disc pommel, the long fine taper and the curved quillons here all belong to the two centuries after him. The name has attached itself to this family of long knightly daggers through trade and collector usage rather than through any documented connection, and we use it because that is what people call the style, while telling you plainly what it does and does not mean.

Two things, and one of them is the reason the shape exists. Quillons that sweep toward the blade rather than running straight put the terminals closer to the plane of your hand, which means an opposing blade sliding down your own is deflected outward and forward rather than simply stopped, and it is harder for a point to travel past the cross and reach your fingers. The hooked terminals continue that: a hook catches where a straight end lets something slide off. The second, more prosaic function is that a curved cross is less likely to snag on clothing or on the mouth of a scabbard as the dagger is drawn, because the sweep guides rather than blocks. On a piece this length that matters more than it would on a short dagger. It is also, honestly, the least common arrangement among surviving daggers of the type, which is why we offer the straight cross as a free alternative for anyone who wants the more usual form.

At 650 grams for an 18 inch blade this works out at 36 grams per inch, which is the lightest figure in our entire dagger range and by a clear margin; the rest run between 42 and 79. Three things produce it. The blade is ground unusually fine from the shoulder, with a slender section rather than a broad one. It carries a fuller down most of its length, taking a channel out of the middle of that already thin section. And the hilt furniture is minimal: a thin curved cross and a flat disc rather than the heavy blocks and cast mounts some of our other daggers carry. The result is a piece that handles far better than its dimensions suggest, and one you can hold out at arm's length without your wrist complaining. The cost is robustness. This is the slenderest blade we make at this length and it will not tolerate being levered, dropped point-first or used as anything other than what it is.

Five pieces on one hilt tradition, and they differ far more than the names suggest. Compare them by weight per inch of blade, which is the number that actually predicts how a dagger feels: this one at 36, our Ball Pommel at 43, our Wheel Pommel at 54, our Barrel Pommel at 63, and our Fishtail Guard at 79. That is more than double from one end to the other. Take this one or the ball pommel if you want something quick in the hand; take the barrel pommel if you want plain, honest work you can judge; take the fishtail if you want an object that announces itself across a room. Length is the least useful thing to choose on, and the biggest one always wins in a photograph.

By hilt, yes; by blade, arguably not, and there has never been an agreed threshold. What separates a dagger from a short sword in practice is not a measurement but how the thing is held and what it is for: a short grip meant for one hand with no expectation of parrying, and a guard that stops the hand rather than protecting it. This piece has both, which is why we call it a dagger. Be aware, though, that legal definitions frequently do use a length figure, and at 18 inches this will fall outside knife legislation and into sword or bladed weapon provisions in a great many places. Our steel lobed bollock dagger page sets out the classification question in more detail.

It removes steel from the middle of the blade's thickness, where the material contributes least to stiffness, so the blade loses weight without losing much rigidity. On a blade this long and this slender the effect is significant and it is one of the three reasons this is the lightest piece in the range. Our deep-fullered kukri page sets out the structural argument, our fullered bowie page explains how to tell a forged fuller from a ground one, and our twin fuller bollock dagger covers why some fullers stop short at the forte while others run the length as this one does.

Both edges as standard. The blade is slender from the shoulder and tapers evenly in both width and thickness to a fine point, with a narrow fuller running most of its length. It is ground for thrusting first and cutting second, which is what the type was for. If a double edge is a problem where you live, we will sharpen one side and leave the other as a blunt false edge at no extra cost, and the piece looks identical.

Sight along it. Every blade tapers in width toward the point, which you can see at a glance; a good one also tapers in thickness, which you have to look for deliberately. Mass removed near the point affects how a blade handles far more than the same mass near the hilt, so on an 18 inch blade this matters enormously: with a proper distal taper it handles like something considerably shorter, and without one it feels dead and nose-heavy however light it is overall. Lay the blade flat and look at it edge-on from the hilt end, and the thickness should reduce smoothly toward the tip without steps. Our twin fuller bollock dagger page sets the test out in full. It is worth applying to any long blade you are considering, from any maker.

We cannot answer that for you, and this piece needs more care than most in our range. Two provisions tend to apply. Many jurisdictions treat double-edged daggers as their own restricted category regardless of size, and blade length thresholds apply independently on top. At 18 inches this is well above any ordinary knife allowance, which in most places means it stops being regulated as a knife at all and falls under sword or bladed weapon provisions, with different rules and different penalties attached. Import rules are frequently different again from possession and carry rules. Check all three for your own address before ordering. If length is the obstacle, a 12 or 14 inch build costs no more and is a commoner historical proportion anyway.

The components are orthodox; the combination is ours. A disc pommel, a leather grip over a shaped core and a cross guard are all correct for a fourteenth or fifteenth century knightly dagger, and the construction follows the period method rather than imitating its appearance. The curved cross with hooked terminals is the least usual element: straight crosses dominate among surviving examples of this class, and curved ones appear but are the minority. So this is a piece built to the type rather than copied from a documented find, and the name is a trade term rather than a provenance. If you want the more conventional arrangement, the straight cross is free on request, and if you portray a particular region and date we will adjust the proportions to suit.

5160 high-carbon spring steel, the same stock our smiths use for kukris and swords, forged down from leaf spring in the Nepali tradition. It is oil-quenched and then tempered back, giving a blade that holds an edge but stays tough rather than brittle. Toughness matters more here than on any other dagger we make: this is the longest and slenderest blade in the range, and a thrust that lands off-line loads it sideways along its whole length. That is exactly the case where a hard, brittle steel snaps and a properly tempered one flexes and returns. It is not stainless and it will take a patina with use.

Close, but not identical. The blade profile is drawn out by eye against a pattern and the taper is ground by hand in both width and thickness, which on an 18 inch blade leaves more room for variation than on a short one. The fuller is cut individually and its ends land slightly differently each time. The curved cross is forged and filed one at a time, so the exact sweep and the shape of the hooks vary, and on this piece that is the element you are most likely to notice. Leather differs in colour and grain. What does not vary is the specification: length, steel, construction, heat treatment and sharpness are held to the same standard on every piece.
