Crimping Tool and Crimp Sleeves
If you have fence wire that's broken you can use a crimping tool and crimp sleeves to repair the wire and splice fence wires together.
Gloves
You don't need specific fencing gloves, but they should be thick, and leather will protect your hands the best for fencing work.
Permanent Wire Strainers
Permanent wire strainers can be used to join two wires in the middle of a fence line. This method is not as strong as using crimp sleeves, but is easy to do.
Post Driver
You can get a post driver that attaches to your tractor, or get a manual one.
Saws
A circular saw will make trimming fence posts easy, but a manual saw comes in handy for any difficult angle cuts.
Spade
You don't necessarily need a specific fencing spade, although you can buy them. A fencing spade is shaped specifically for post holes, but unless you are digging a lot of postholes, your standard garden-shed spade should do the trick.
Staplers
Stapling is an important part of fence construction, and one that can determine its durability. It is therefore important to use good stapling gear. You can get staples and staplers specifically for fencing, and you can get staplers that use staplers or hog rings.
Tape Measure
Never start fencing without one. Or two. It can be handy to have a shorter and a longer tape measure.
Wire Cutters
Used for cutting high-tensile wires, it's a good idea to invest in a good-quality pair.
Wire Dispensers
It's important for fence wire to be dispensed uniformly to avoid damage. Fence dispensers help with this process.
