Kon Tam Krok Mong (Mortar-pounder Toy) — bamboo base, bamboo mortar, joints with wooden pegs, a paddle-shaped lever with two drilled holes; pressing the lever raises and lowers the pestle, like pounding rice.

Select a whole bamboo segment for the base, cut bamboo to make the mortar, and attach it to the base with glue. Use scraps of hardwood to make the head, arms, legs, and pestle. Use a small bamboo segment for the torso, drill holes at the joint points, and insert wooden pegs as fasteners.

Drill holes in the base, insert the figure, beam, pestle, and pillar into the base, then add glue.

Sharpen a bamboo stick to resemble a boat paddle. Drill two holes: the hole at the base is made into a fulcrum at the base; the hole at the tip connects to a wooden shaft fixed to the pestle above. This mechanism is a spring lever and pry bar.

Press the seesaw lever down, and the vertical stick will move up, similar to a person's foot stepping down on a mortar pestle

The creator of this toy made it to illustrate the rice-pounding process for children. However, rice pounding was already part of daily life, and no instances of it being made into a toy were found. Currently, only 1 person can make it. Be careful with the knife while whittling the wood.
