How to attach a handle
Heat the 'Nakago' of the kitchen knife with fire and insert it while balancing the angles. Tap the bottom of the handle with a mallet to insert the core, and then tap the insertion hole to remove it.
Keep the balance and put it in an appropriate depth.
The reason why the Nakago is heated with fire is to bond it with the burned holes in the handle. When the heat cools, the wood and buffalo shrink and the Nakago does not come off.
