Add planes on both sides to set to self-luminous, cancel camera visibility, and do physical movement. The streamer effect can be achieved.

Add two bodies, give the section material and then exclude the object, and translate to both sides to achieve the effect of the blade coming out.

The movement of parts is basically to set the lens first and then adjust the movement position parameters. The relaxation movement can also be adjusted in the Keyshot, or in the Pr software tuning function line.

Fragment synthesis (Pr software),Ps can also do basic synthesis.
