Here's my tool presets with brushes, erasers and so on
PS CS6+ only!
How to use:
1. Choose in Photoshop Window - Tool Presets
2. Put a tick on the bottom left
3. Click drop-down menu at the top right, choose Replace Tool Presets
4. Select the downloaded .tpl file
Now, when you select the Brush tool, all available brushes will appear at the Tool Preset window (and when you choose Eraser tool - there will be erasers).
Alt + click on the tool title - remove tool; create a new (save the selected brush settings) - click the icon at the bottom of the panel.
