Study the drawings first.

Look at the drawings, pick the mold,

Remember the mold shape.

Look at the folding, choose the machine tool,

Install the mold. Don't be busy.

The locking pair is on the center.

Look at the blueprints, the row of knives,

Good knife sequence, high efficiency,

The principle of knife order is easy to remember,

Fold forward and fold back without conflict,

It's comfortable to fold in and out.
