The full list of its bearers is unknown, but the first bearer known by name is Giacomo Paradisi, who won it in a fight with the previous bearer, and lost the two small fingers on his left hand obtaining it. The knife was made by philosophers of Cittàgazze, from the Torre degli Angeli, who cut many windows in their world. It is unknown if the reforging has been attempted since. The second breaking of the knife was purposeful, and left the blade of the knife in shards once again. The knife apparently held the ability to kill Spectres, as Will managed to stab one with it causing it to fade away. However, the knife's abilities weren't impaired even the slightest as the result, as it was still immeasurably sharp. Will considered the end result to be 'ugly'.

Its handle was charred from the forge fire, the blade shortened as the result of the smithing process, and left with the perpetual dark seams on the places where the shards were connected. Although Iorek Byrnison was able to reforge it the first time, it altered the appearance of the knife. It was the belief of certain individuals that this was because the knife was incapable of cutting through love.ĭue to this, the knife was broken on two separate occasions. No known material was able to resist the knife, although it was breakable, should a wielder attempt to use it whilst thinking about a person they loved. The knife also possessed a special leather sheath with straps meant to hold the knife in place while not in use, as it could effortlessly cut through even the thickest leather. The wire was slightly elevated from the wood of the handle to ensure a firm grip on the weapon. The handle of the knife was made out of wood and adorned with the relief made out of golden wire in the shape of an angel with spread wings on one side, and the angel with closed wings on other side.

The other side was made out of what Lyra assumed to be the same type of metal used in intercisions (which would make it a manganese-titanium alloy) and was described to be 'shade-coloured.' This side of the blade had an edge even keener, narrow to the point neither a human nor panserbjørn (who was a master blacksmith) could perceive it with the naked eye, and had the ability to 'feel' the gaps in the fabric of multiverse and use them to cut through the fabric, thus opening portals into alternate universes. One side of the blade was made out of steel and had the edge so keen, it could cut through any physical material with negligible resistance. The knife was described as common looking with short, dual edged blade, made out of two different metals.
