Aikiken long sword
The Aikiken wooden long sword (bokken) is available in 2 sizes and combines the necessary speed and strength required in paired Aikido weapons work. The medium version is arguably the best representation of the benchmark or average size and shape of a bokken. At 40" overall length and medium girth, it could be used in most dojo and most practice situations for martial artists seeking a mid-weight design. The Aikiken large is slightly larger in both length and girth.
These bokken are shaped for precision and maneuverability but specifically designed for techniques involving contact with other wooden swords or staffs. Many aiki sword techniques rely on the size and mass of the bokken for its ability to deflect and redirect energy from the strikes of other wooden weapons, at least to some degree, and the ideal bokken must be heavy enough to effect the path of another weapon, yet be well balanced and light enough for reaction speed. The large aikiken is 42" long overall, fairly stout in profile and has a 11 1/2" tsuka. The medium aikiken is 40" long overall with medium proportions and 11" tsuka.
The Aikiken bokken has a pedal shaped transition. It allows for the use of a tsuba (hand guard) but also creates a tactile reference for hand placement. Optional inscriptions are made on the bevel, right in front of the tsuba position.
This is the chisel shape of the aikiken kissaki (point). It's derived from koryu (old school) designs and while the geometry is very strong, the shape gives the user a very good visual reference of it's positon and orientation.
