The Park CT-3 Screw Type Chain Tool is now made from investment cast tool steel. Along with superior strength and durability, the CT-3 features a handy "loosening shelf" to remedy stiff links after reassembly. The fine thread and comfortable size enable easy removal of even the toughest chain rivets. Like all Park Tool Chain Tools, it's easy to use and built to last, and has a replaceable driving pin.

This guy is a real brute and makes fast work of breaking any chain. Re-inserting chain pins is another matter, I’d imagine even trying to do so on a 10s chain would be an exercise in frustration. But on hard-to-handle 1/8" track chains, this guy is perfect, and honestly I’ve never had occasion to try inserting a pin on a 10s chain due to the prevalence of tool-free master links. Build quality is as awesome as you might expect, and the replaceable pin is a great feature (I though that was ridiculous when I bought this-- who ever bends a pin on a chain tool? But then I bent the pin the second time I used the tool).

Great tool but has a few design issues. Works great on 8, 9 speed chains and track chains (PC-1) even though the the CT-7 was specifically designed for BMX/fixed gear chains.
I destroyed a KMC 10 speed chain with this. When pushing the pin back through, it causes the rear plate to mushroom out.
The circlip that prevents overdriving the screw is a POS. Always has been an issue and should be redesigned. Bought a replacement from a hardware store that fit better and lasted longer but its bent and loose now.

Excellent chain tool -- the best I’ve used. No problems with 9 speed, but I haven’t used on a 10 speed chain.

I just destroyed a 10-speed Dura Ace chain with this tool. The anvil is too wide and the pin widens the back plate hole. I’m not sure what I’ll do, maybe use the IRD link or the Shimano-brand tool.

The CT-3 chain breaker is a spectacular tool. I go through a 10 speed chain every 1.5 to 2 months (approx. 2,000 miles). This tool breaks the chain quickly and effortlessly. While my smaller Park CT-5 chain tool is great for the saddlebag on my bike, the CT-3 tool is an awesome addition to my toolbox. It helps me easily mount a new chain. Well built, sturdy, and highly recommended.

I just picked up one of these from Excel and I have to say it’s the best 25 bucks in my toolbox. You might think, "This thing is overkill, I only have to break two or three chains a year." That’s exactly why you should buy it. Oh, sure, half an hour of aiming the pin of some $6 chain tool will get the job done as long as you regularly replace its bent pin, if not the whole tool. But you could also use a CT-3, which doesn’t require the aim of Robin Hood and will last long enough to be passed on to your children.
