Being a mechanic is one of the few jobs where you have to supply your own tools to do the job eveb though you're not self employed. My brother built up a really nice set of tools, the majority of which were Snap-On including the cabinet and then had the lot stolen from the workshop. He then found out they weren't covered on his employers insurance.
Can you imagine turning up for a new office job somewhere and being told you've got to supply your own desk, chair and computer and if any of them brake you've got to replace or repair them yourself.
