Is the Park Tool CT-5 Compact Chain Tool worth carrying?

The Park Tool CT-5 Compact Chain Tool is a pocket-sized chain breaker built for on-the-road and trail-side repairs. Despite its compact form factor, it handles the full range of modern chain widths from 5- through 12-speed, using the same hardened steel pin drive design that Park Tool builds into its full-size professional chain tools.

The folding handle keeps the CT-5 safe and snag-free in a jersey pocket, saddle bag, or handlebar pack until you need it. When a broken chain threatens to end your ride, this tool has the precision and build quality to push the pin cleanly and get you rolling again. It is small enough to forget you have it until the moment you need it most.
