Tips, tricks & notes:

• The crystal saw raises construction three levels. It can be used along with either construction tea or Evil Dave's stew for increased effect. The boost only applies when actually using a saw for making furniture: not for gardening, building rooms, or buying monsters.
• After building exactly 28 construction items while carrying it, the crystal saw will revert to seed form. Use the seed on the Singing Bowl again to recharge the saw.
