Work Speed Coefficient

Work Speed Coefficient (WorkSpeedCoefficientWhenBeMain) is a Property of Materials that determines their effectiveness as a Tool. It affects most types of Tools that can be made from different Material types, and acts as a multiplier on their base effect. 
Tools that are affected by Work Speed Coefficient are not affected by the Quality, Element or Tier of the toolXiaWorld.NpcEquipData.ActiveItemThing, and therefore there is no improvement from performing Specter Refinement on the tools.
Tools that can only be made from Cloth or Leather are affected by Work Speed Coefficient, but the material does not change their bonuses, since all Cloth and Leather Materials in the game have a Work Speed Coefficient of 1Settings\ThingDef\Item\Item_Material_Leather.xml, Settings\ThingDef\Item\Item_Material_Cloth.xml. This does not apply to Clothing, which do vary in bonuses with different materials, as its bonus is classified as a Gear and not a Tool.
Early to mid-game, Spiritwood (Timber) and Darksteel Bar provide the highest Work Speed Coefficient for easily obtainable materials at 2.0x bonus, and mid to late game Parasol Timber and Lumina Core Bar items have the highest Work Speed Coefficient of all materials at 3.0x bonusSettings\ThingDef\Item.
