A bushing wrench is a lot easier to keep track of and a lot harder to break. I have a bushing wrench in my glove box still and haven't carried a 1911 in a few years. The last bull barrel 1911 I had I broke the takedown tool the second time I field stripped the gun.
Also, I have had some REALLY tight barrel bushings on 1911's and in a pinch if you simulate a stovepipe malfunction(pull slide back slightly and insert spent casing in between the breech face and the slide) you can then just push the recoil spring plug in and turn the bushing with your fingers pretty easily. Try it even on a 1911 that you don't necessarily need a bushing wrench for, you'll be surprised just how much easier it really is.
