How does a Speed Cube work_ (2)

Corner and Edge Pieces: The corner and edge pieces of a speed cube are designed to reduce friction and provide optimal movement. They often have rounded or chamfered edges, allowing for smoother corner cutting (when one layer is turned while another is held) and reducing the chance of pieces catching or locking up during solves.

Lubrication: Speed cubes are often lubricated with specialized silicone-based lubricants to reduce friction and enhance the turning speed and smoothness. Different lubricants can be used for the core, pieces, and even the screws and springs, depending on personal preferences and desired performance.
