Yuen Kay San Lineage Wing Chun Butterfly Swords (Sifu's Series)
(a.k.a. Wing Chun Butterfly Knives, Bart Jarm Do, Bot Jaam Dao, Hudiedao)

The Yuen Kay San Butterfly Swords are a very limited edition collector's item (only 3 available to the general public) commissioned by Sifu Alton Miller. They are beautiful and very comfortable 12-inch stabbers.

Own a piece of Wing Chun history. These are a duplicate to a Yuen Kay San design cherished by Sifu Alton Miller. The knives are an outstanding combat weight - around 700 grams each (1.54 lbs).

The blades are made of custom knife-maker quality Bohler D-2 tool steel, professionally heat treated to weapons-grade. On the blunt part all edges are 1-2mm. On the sharpened pairs the swage on the spine is sharpened - so be careful if you flip them. These are real weapons, inherently dangerous and should be treated as such at all times.

The handle on these knives is roughly centered on the blade, a location optimal for percussion against armored targets. They can be flipped between a forward and reverse grip but it is not as easy as when the handle is aligned on the spine. These knives have two-in-one full tang handles of black laminated dyed stabilized wood but full (i.e., two-sided) blades.
