That's actually the Pedro's Six Pack.

In a previous reply, I had shown a picture of a cheap eBay chain tool that looks very similar. Having just taken the time to test it out, I cannot recommend it, for a couple of reasons.

Though it looks identical to the Pedro's, mine came with a slightly bent pin. That might not have been a problem, but the slot to press the rivet in through is very tight. With a bent pin, the rivet is no longer centered over the slot, so you're just trying to press it straight against the tool. Finally, the quality of metal used is pretty poor. Even after centering the rivet on the slot, it was very difficult to press the rivet out. It seems the threads were getting mangled (yeah, technical term) when trying to press the pin in. I was actually able to press the rivet out after greasing the threads.

This is no reflection on the Pedro's Six Pack. The reviews of it have been very positive and I'm sure it is made to much higher standards. Just going by the pictures, the finish is nicer, probably because it is also made with a better material.

So there you go, a cheap eBay tool doesn't compare to the part it's undercutting by over 80 percent.

Also, this goes to show, you should really test your tools before thinking of depending on them on the road or trail.

Finally, in my previously mentioned post, I said I'd test the Mineral Design Barstow. It had no problems with the same chain I tested the eBay special on. I'm unsure whether I will get more of the Barstow, buy a Six Pack, or experiment with something else. The Industry Nine Matchstix looks appealing, but I don't have any thru axles to use it with anyway.
