Faucet change-out tool

I couldn't get to this nut by hand under the sink. I actually broke the wing on the nut a little trying. I made this, giving myself knurling on the round part to turn by hand, and square on the bottom to grab with the channel lock pliers. I ended up having to use the channel lock pliers to get it loose because there was so much corrosion, but it worked.

I heard it crack a little on the inside - or at least I think it was the tool. I suppose it might've been the fixture. It looks fine on the outside, though, and got the job done.
