How to disassemble the glue injection handle in Shancheng?

I need to buy a set of mountain city hand-made clothes, which is very cheap, about twenty, including a small copper hammer, which can be used to push out the nails on the handle, then press the fingers on the knife with the right hand and shovel it with the left hand to make the knife disintegrate.

Because the shancheng hilt in Japan is beautifully made, the blade is clamped with upper and lower battens, that is to say, every inch of the hilt is attached to the blade, and a good knife is equipped with a blade and a hilt.
