Description
Read this listing before you buy. Both edges of this blade are ground and sharpened, which changes how the knife can be handled and rules out a large part of the standard trick vocabulary. It is a beautiful object, a symmetrical Damascus spear point on rosewood between polished brass, and it is the least forgiving knife we sell.

A double edge changes the rules
Nearly every balisong has a safe handle, the one that meets the spine, which you can catch, slap and grip mid-flip without consequence. This knife does not have one. Both edges are sharpened, so both handles are live, and every trick that depends on catching the safe side has to be relearned or given up. That is not something we are burying in the small print. It is the single most important fact on this listing. Buy it to display, or buy it knowing you will be flipping far more carefully than with anything else you own.
Why anyone builds one
Symmetry. A double-edged Damascus blade puts the forge pattern on two ground bevels instead of one, and the etch reads continuously around the whole profile rather than stopping dead at a flat spine. Held up to a window, the layer bands mirror each other across the centreline. This is the version of the blade that photographs best and the version that flips worst, and those two facts are the same fact. Most owners of one of these keep it out on a stand rather than in a drawer.
Rose wood between brass bolsters
Brass at the pivot ends does two useful things on a double edge. It adds mass exactly where you want it for control, and it puts the softer, easily refinished metal at the point of impact when the knife meets a hard floor. The rose wood between the bolsters is dark, tight-grained and set flush, so nothing catches a finger during a rotation, which matters more here than usual, because the alternative to a clean grip is an edge. The single-edged version of this handle is the safer buy for a flipper.
Two edges, twice the sharpening
Everything you do at the stone, you do twice, and you have to match the two sides or the point wanders off the centreline. Simple forged layers make that easier than a modern alloy would, since the steel comes back quickly and shows you what you have done. Work a shallow angle, count your passes on each side, and finish on a strop.
Keeping the pattern crisp
Etched carbon steel darkens where skin touches it. On a display piece that shows up first as a thumbprint on the flat, so handle it with a cloth if you are precious about it, or handle it freely and accept a patina. Neither approach hurts the knife. A dry wipe and a thin coat of oil before it goes back on the stand is the whole of the maintenance.
Sheath, law and bench
The sheath is black leather with a stamped face and a press stud, and the channel between the handles is cut deep enough that both edges sit clear of the wood when closed. Balisong rules vary by state and country, so confirm yours before ordering. Forging, grinding, etching, fitting and sharpening are done at our shop in Memphis, and our lifetime warranty follows the knife.
