Stone Cutters are used to convert raw Stone Slabs into Stone Bricks. It is found in cities nearby trainers, often nearby resource fields and in buildable structures on player owned plots: Stoneworking Shop.
Machines on player owned plots/lairs give a bonus to related skills. The bonus is available for crafting purposes and is only shown in the creation window, not in the character skills window. If you are a few points less from being able to scribe a formula you can use the shops to scribe as long as you follow the simple rule of using the creation window.
Example: You want to scribe Expert Mining Pick (800 Metalworking) required. You are at 753 Metalworking. Simply act like your going to make an item that uses Metalworking, i.e. Journeyman Mining Pick, while standing next to an Expert Anvil. Be careful not to have a tool in your hand which may limit your skill. When the Creation Window opens, you will notice an increase in skills by below mentioned bonuses, boosting you to over 800 at this point. Leave the window opened, open your inventory and scribe the Expert Mining Pick formula.
Bipedal (Plot) bonuses
Dragon (Lair) bonuses
