Material Choices – The Blade

Kama blades are available in either aluminium, stainless or heat-treated steel.

Aluminium is almost three times lighter than steel (each blade is ~94 grams) and fully corrosion resistant, however as a softer metal it is more vulnerable to scratches. These blades are recommended if you would prefer lighter-weight equipment or for a beginner’s training.

Steel is a denser material and therefore heavier (each steel blade is  ~265 grams).  The additional weight of steel gives a traditional heft to the weapon and assists in developing strength, however these kama are recommended only for the more experienced practitioner.

Steel may gradually oxidise if left in contact with moisture.  Heat treatment hardens the metal and provides a corrosion resistant black coating on the body of the blade. For untreated blades, an occasional wipe with a thin oil will help preserve the surface.

Material Choices – The Handle

Design – The Blade

Kama - Aluminium & Walnut

The Seaholme blade design has been developed based on existing martial arts kama, modified for safety. The sharp point seen on some blades is rounded off and the ‘cutting edge’ is completely flat and unsharpened.  Both steel and aluminium are 4 mm thick.

A 1 cm bevel is ground for appearance only; these kama are for demonstration and will not be supplied sharp.

Design – The Handle

The handle is profiled with the classic ‘stadium’ shape.  Flat sides allow for control when changing hand position.  Rounded sides provide a comfortable fit in the hand.

The standard length 370 mm (measured butt end to top of ferrule) and width 32 mm x 26 mm.  This can be customised on request.

Construction

Kama are built to last: solid wood handles joined to a steel or aluminium blade, using traditional ‘hammer & anvil’ peened 4 mm diameter through-rivets and a 27 gram brass ferrule.  Handles are finished with multiple coats of hand-rubbed natural tung oil.
