At the moment, the citizens of Klondike are strongly engaged in its restoration after a massive avalanche. Because of this, you can experience a lack of tools and important materials. You can get hammers, saws or trowels:
1) in a daily Bonus,
2) by completing orders from Sir Chaney,
3) for completing Trader's orders.

Note that Sir Chaney doesn't come every day with orders (he doesn't like queues)... But if you complete orders from other characters, every 5th or 6th order will be from Sir Chaney.
