There are now many designs and styles of firefighter axe belts and holders that you can buy online. However, there are some things you’ll need to consider when buying for the right axe belt or holder. For a start, it should be made of high-quality and durable leather material. This is to ensure that no matter how heavy your axe can be, it can be able to carry it. 
Real leather also doesn’t burn easily even when it gets near the flame, unlike synthetic materials that can combust when it’s exposed to high temperature.
Your firefighter axe belt should also have a swiveling holster that can rotate up to 360 degrees. A holster will keep your axe head well secured and the blade away from your skin. But a swiveling holster will let you position your axe in the direction where it would not hinder your movements. 
Again for the holster, it would be great if you could find a belt with an adjustable holster that can hold up a standard size pick-head axe and flat head axe.
We also suggest that you choose a fire axe holder or firefighter axe belt with a metal buckle and not made of plastic materials that can break if you pull your axe hard. Needless to say, the leather belt should also be thick and wide, probably more than 2 inches wide.
Lastly, for your axe to be easily accessible, the holster should have an easy flip cover with a Velcro for the lock. Some people who don’t like synthetic materials on their holster lock choose the magnet buttons.
