An axe is an invaluable tool when you venture out into the wild, or even camping.
I always carry one with me for my camp. Mostly it's a hatchet. I would only take a larger axe for the jobs at hand.
As I have said before, a knife is always must to take out with you, but pair it with an axe, it makes the work easier.
Of course as with a knife, a sharp blade is essential. The same goes with your axe. I wouldn't try chopping or splitting with a blunt axe, it would need more effort and can be very frustrating. Also very dangerous, as a blunt axe would miss or slip more, causing accidents.
Here is a guide to sharpen an axe, at home or in the wild.
You will need to protect your hands and face. These are the steps to avoid any accidents while sharpening an axe:
Wear thick leather gloves or you can get some safety gloves
If you are using a file, make sure it is in good working order, with a handle is best.
Wear safety goggles or glasses to protect against any metal particles.
If you want to wear a mask, go ahead, but if you will be using a power tool a mask is a must.
There are so many videos on the web on how to sharpen your axe. I will be updating this section, once I have my work bench in place. So you will have some good solid and safe ways to sharpen your axe.
In the meantime have a look at wikihows website about sharpening axes. Here is the link.
