How to make hands do no damage to blocks

[Muggles]

Using 1.8, is there a way that I can set the default players hands to have a harvestLevel of 0, so that they can't actually mine anything without the use of a tool (which of course I will have spawn with them)? I have been looking around for a while and couldn't find a way to do it, even with editing base files (which I wouldn't mind doing because I'm doing a total conversion of minecraft). Any suggestions/ideas? Thanks.

use BreakSpeed event, check if the player is using bare hands, if he does set speed to 0

I hate to be "that guy" asking you to explain in more detail, but could you explain that just a tad bit more please? As in, where do I use the BreakSpeed event? Thanks
