There are many tools in the paracord world that are necessities for perfecting your craft. Three particular ones come to mind. The fid (I use it with most projects), Knotter's Tool, and the Spool Tool.
Fids are traditionally made of bone or wood--obviously the most readily available materials to people living in the rural parts of the world. The basic idea behind a fid is similar to that of a needle—to enable the individual to weave something that they are otherwise unable to weave with their hands—but with rope or cord rather than thread. This ability is particularly important when working with Paracord, because of how fine the cord is and how tight the weaves generally are.
A fid is a small tool that can make a world of difference in your paracord projects. It's most basic use is for weaving paracord into spots that you can't do with just your hands. It can give your projects a much cleaner and professional look if you're able to tuck in the last of the cord, rather than ending it abruptly in the front of your item.
Two particular bracelets where a fid is basically a necessity is the Awareness Bracelet and the Rainbow Bracelet. With the tightness that a paracord bracelet usually is, it would be nearly impossible to weave paracord back through it.
Fids also give you the ability to weave micro cord through a bracelet without disrupting the weave.

A similar tool is the Knotter's Tool (AKA tightening tool). Our comes with 3 different sized fids inside. This tool is used for loosening paracord that you aren't able to do as easily with your hands. You're really able to dig under the cord and loosen it quickly and easily with this tool.
Another tool to have in your paracord toolbox is the Spool Tool. This simple little device holds up to 100' of 550 paracord and features everything you need to measure, cut, and heat-seal the ends. No more tangled line, no more missing tools, and no more melted globs burning your finger tips and sticking to your gear. The Spool Tool can also securely hold a mini BIC lighter for heat-sealing paracord. It's also small enough to carry in a cargo pocket or backpack pouch.
