Yes, a chain whip and a cassette lockring tool work as a pair; the lockring tool alone can't remove a cassette because the freehub will just rotate with it unless something is holding the sprockets still, which is exactly what this chain whip does.

Wrap the length of chain around a sprocket a few teeth away from the lockring in the direction that resists pedalling force, then hold the handle firmly while you turn the lockring tool with a wrench in the loosening direction.

Yes, using a chain whip alongside a lockring tool is a standard, learnable home maintenance skill, and having both on hand lets you clean, replace, or upgrade your cassette without a shop visit.

It's built from a steel bar with a length of chain riveted at one end for wrapping around the cassette, and a textured handle for a secure grip during the high-torque moment of breaking a tight lockring loose.

Wrapping the whip's chain around the correct sprocket and pulling in the right direction avoids damage; wrapping it backwards or on the wrong sprocket can slip or mark the cassette teeth, so it helps to check the direction before applying force.
