Saw (GregTech 5)

By default, GregTech reduces the yield from shapelessly crafting Wood into Wood Planks from 4 Planks down to 2. The Saw undoes that. When Wood is crafted with a Saw, it yields 4 Planks; when 2 Planks are crafted with a Saw, they yield 4 Sticks. The Saw is required to craft Wood Slabs and Wood Planks (singular). Importantly, the Saw is also used as an early way of acquiring Bolts, which are then used to make Screws.

The Saw can also be used to break blocks like an Axe, however it is significantly slower.

Using the Saw for crafting will consume 200 Durability, while using it to break blocks will consume (50 * Hardness) Durability.

If the GregTech 'WoodNeedsSawForPlanks' configuration is disabled, using a Saw will increase Plank and Stick yields from 4 to 5.
