Tinker's Crushing hammer doesn't seems to level or no alt key

Current version: 1.8.4.1

Issue: It seems the tinker's hammer doesn't level like other tinker's tools. There is no ALT key feature to show current experience level.

Desired change: make the crushing hammer auto level like other tinker's tools.  If it is set to level please ensure ALT bound key shows exp levels.

Thanks.
