 Shovels are tools for digging coarse blocks, such as dirt, sand and gravel. They can also be used to turn grass blocks to grass paths. Shovels can be used as weapons, but they are very weak.=Schaufeln sind Werkzeuge zum Ausgraben von groben Blöcken, wie Erde, Sand und Kies. Sie können auch benutzt werden, um Grasblöcke zu Graspfaden zu verwandeln. Schaufeln können als Waffen benutzt werden, aber sie sind sehr schwach.
 To turn a grass block into a grass path, hold the shovel in your hand, then use (rightclick) the top or side of a grass block. This only works when there's air above the grass block.=Um einen Grasblock in einen Graspfad zu verwandeln, benutzen Sie sie auf der Oberseite oder einer Seite eines Grasblocks. Das funktioniert nur, wenn sich Luft über dem Grasblock befindet.

Shears are a special mining tool and can be used to obtain the original item from grass, leaves and similar blocks that require cutting.=Eine Schere ist ein Werkzeug, um Schafe zu scheren und ein paar Blocktypen abzubauen. Sie ist ein besonderes Grabewerkzeug, das benutzt werden kann, um den ursprünglichen Gegenstand von Gras, Blättern und ähnlichen Blöcken, die abgeschnitten werden müssen, zu erhalten.

Gesichter können nur an der Seite von gesichtslosen Kürbissen eingeschnitzt werden. Das Abbauen funktioniert wie bei anderen Werkzeugen, nur, dass die Abwürfe für ein paar Blöcke anders sind.
