I have both the Bikesmith tool and the Harbor Freight tool. I really like the former and am not about to make any complaint about it. But there are times when the Harbor Freight tool is better. On my Raleigh Lenton Sports, for example, the Bikesmith tool couldn't get close enough to the chain ring, so couldn't press the drive side cotter out straight, and I'd bent it before I realized what was happening. It should have worked on the other side, but it bent that one over as well. After drilling a guide hole into the remains of those, the Harbor Freight tool popped them both out without further trouble; but I had to grind off the ends of the jaws of the latter so it could get close enough to the chain ring.

I did not modify the pusher of mine; I only drilled out the hole at the receiving end and ground the edges off the jaws. It is not the better tool in most cases, but in really tough cases it is the right tool for the job.
