Getting hand drills
A sure way to get a hand drill is to buy it with 10 dia.
Hand drills can also sometimes be found in roadside shops for 1 to 342 coin per drill.
Finally, hand drills can be randomly obtained when players:
- open mystery boxes and mystery packages
- spin the Wheel of Fortune
- fully satisfy a town visitor
- win prizes in derbies
- use mystery nets in the fishing lake
- watch a Night at the Movies trailer
