Tonfa Sizing

 If you are a school or organization Crane Mountain makes a tonfa measuring stick for sale at a nominal fee This stick allows you exact measurements of the hand and elbow length.

      An alternative method of measurement, is using a carpenters square. By gripping the square’s narrow

column as illustrated by the drawing below. The length of the elbow can be obtained by the inside square measurement plus one half the thickness of the column.. The measurement for the hand can be obtained by the inside tick marks of the column and subtracting the 1/8th of an inch.

 

     The measurements to use when calling in an order are : 1) The elbow length and 2) the hand size.  Specify the elbow length plus extension beyond the elbow your school or system requires.  It is typically an inch for most Kobudo schools.  Please give us the elbow size and extension as 2 separate  measurements. I.E. 13 + 1. Standard sizes for handles are in 1/4 inch increments and blade lengths are in 1/2 inch increments. Extra  charge for custom lengths outside these parameters.
