I'm always shocked when people don't know this, but surprisingly, many don't. The nylon balling twine they use nowadays on rectangular bales can be cut with friction. Just find a length that's laying around from previous bales (or I always keep some in my truck since it comes in handy for lots of things), and string it through the twine on the bale. Then just see-saw it back and forth on the same spot several times and it'll cut right through. (Anonymous)
If you're not using quick release snaps on your halters, this is a precaution you can take. If a horse pulls back while tied and falls down, then can't get up, it can be pretty sticky trying to get in there and release him. If it takes you too long, he can start thrashing around and hurt you. We never tuck the strap end into the buckle on our halters. It's a lot faster to be able to grab that strap at his head and pull up to release the halter than it is to try to release a rope that's bit down on itself. Even quick release knots aren't quick anymore once that happens. (Anonymous)
