Jackhammer

Be cautious of how you aim the tool. If after mining a node and you're aiming towards the ground, the few times you hit the ground it will take a decent chuck of durability with it.

If you tap hit a node it will continuously proc the sparkle, saving durability compared to holding.

Can be "Refilled" when in distance of any workbench. (Level 1, 2, or 3) Go into your inventory and click on the jackhammer, and above the "drop" button, click refill. It does not cost anything. Can also be repaired at a repair bench, however it costs materials.

Useful tool to quickly get rid of a Stone Wall in your base (soft side), either to expand or to change the layout. It will damage the Jackhammer quite severely though.

You can buy a Jackhammer at Outpost(Safe Zone), for 150 Scrap.

Refill (Workbench - free) the jack hammer rather than repair (Repair Bench - mats). The refill doesn't damage the jackhammer as much as repair does. Refill will make the tool last longer. :3

1) If you just hold on left mouse button while farming a node, you will collect about 76 nodes before Jackhammer breaks 2) If you click periodically with jackhammer (two hits on node per click) you will farm 130 nodes before jackhammer breaks 3) If you click periodically and turn jackhammer away right after click (so it only does one hit per mouse click) you will farm 185 ore nodes before jackhammer breaks. P.S. Method 3 is also the fastest. Method 1 is the slowest.

1)You can raid softside stonewalls with these very easily.
2)If you have acces to an enemy workbench, you can raid floors on the enemy base.
4) Looks funny and is deeply satisfying when you hit a corpse with it.
