Good practice

Fit masks or sheaths to axe heads and saw blades, which should fit securely. Do not plant the head in the ground. An axe can be masked temporarily in the chopping block but make sure that the blade is securely wedged in the grain of the wood and that the haft does not pose a trip hazard. Saws are usually supplied with plastic clip-on masks that fit over the blade. Alternatively, make a mask from a split length of hosepipe.
Keep axes and saws dry, and never leave them out overnight. Keep them in a stores tent in a locked box.
Maintain axes by sharpening them regularly, ideally after use and before putting them in storage. Saw blades are relatively cheap and can generally be replaced rather than sharpened. Treat axe heads and saw blades with gun oil or camellia oil to prevent rusting. Protect wooden handles by rubbing them with boiled linseed oil.
