If you happen to see a shop's workspace, chances are pretty good that Park Tool's CT-3 Screw Type Chain Tool is occupying coveted pegboard space. The combination of effective mechanical practices and utilitarian design have made this chain tool a shop staple, and a home mechanic favorite.
It's compatible with 5, 6, 7, 8, 9, and 10-speed chains and features a loosening shelf to free stiff links common with chain assembly. The body is constructed from cast steel and the precision screw features replaceable pins to extend the CT-3 Screw Type Chain Tool's usable life. For comfort, the T-handle is coated with rubber in the signature Park Tool blue.

Reliable, solid addition to the toolbox
- Familiarity: I've used it several times
Sure, the Park Tools products aren't cheap, but they do the job very well, are reliable and last; which must be why I find a growing number of them amongst my collection.
Only used this on Shimano 10 speed chains, but this does the job very nicely.
