&lt;br /&gt;
&#039;&#039;&#039;Steel axes&#039;&#039;&#039; are tools used for the manual mining of resources, for cutting trees, and for collecting items deployed on the ground (so they be placed elsewhere). They can also be used for melee fighting when the player is out of ammo.&lt;br /&gt;
&lt;br /&gt;
They are used throughout the game after [[Steel processing (research)]] becomes available, primarily to move deployed items, since automatic mining of resources with drills is far easier and trees tend to be cleared in the early part of the game. &lt;br /&gt;
&lt;br /&gt;
It is possible to stack multiple Steel axes in the tool slot.&lt;br /&gt;
&lt;br /&gt;
== Durability ==&lt;br /&gt;
&lt;br /&gt;
Durability of the Steel axe is consumed based on the &amp;quot;mining hardness&amp;quot; of what is being mined, at a rate of&lt;br /&gt;
&lt;br /&gt;
&amp;lt;code&amp;gt;Durability loss = Mining hardness * 60 * Duration (s)&amp;lt;/code&amp;gt;&lt;br /&gt;
&lt;br /&gt;
For example, mining one coal that has a hardness of 0.9 and takes 1.08 seconds to mine consumes&lt;br /&gt;
&lt;br /&gt;
&amp;lt;code&amp;gt;Durability loss = 0.9 * 60 * 1.08 ≈ 58 durability&amp;lt;/code&amp;gt;&lt;br /&gt;

{{:Infobox:Iron axe}}&lt;br /&gt;
&lt;br /&gt;
The Iron axe is a tool used for the manual mining of resources, for cutting trees, and for collecting items deployed on the ground (so they be placed elsewhere). They can also be used for melee fighting when the player is out of ammo.&lt;br /&gt;
&lt;br /&gt;
They are mostly used in the beginning of the game where the player has no resources to set up drills to automatically mine, and when the better [[Steel axe]] cannot yet be made. It is possible to stack multiple Iron axes in the tool slot.&lt;br /&gt;
&lt;br /&gt;
== Durability ==&lt;br /&gt;
&lt;br /&gt;
Durability of the Iron axe is consumed based on the &amp;quot;mining hardness&amp;quot; of what is being mined, at a rate of&lt;br /&gt;
&lt;br /&gt;
 Durability loss = Mining hardness * 60 * Duration (s)&lt;br /&gt;
&lt;br /&gt;
For example, mining one coal that has a hardness of 0.9 and takes 2.08 seconds to mine consumes&lt;br /&gt;
&lt;br /&gt;
 Durability loss = 0.9 * 60 * 2.08 = 112.5 durability&lt;br /&gt;
