This is a larger kunai than my previously posted one. It has a fairly heavy blade, a thick handle and the identifying loop on the end of the handle.
Step 1: Handle
to make the loop easier to get a finger into, use the two-piece hinges (usually blue and black/green) in place of the red 90* pieces
Step 2: Blade
note: snap the pieces on before connecting them with the green rods, its much easier
Step 3: Joining the Handle and Blade
slide the handle onto the bottom of the blade, lining up the holes. insert the blue rod having the pin on the tan connector in the middle slot, add the other tan connector, pin on the inside. add the black piece to lock it together. kunai complete!
