Hey!
This update really looks cool and improves VS significantly in the right direction!
I would however gladly trade this grinding wheel crit bonus for tool repair. VS is pretty realistic and I don't like the fact that every metal tool is not repairable and durability is so low.

You can repair a tool but overall durability is reduced each time (configurable), so you need to replace it one day anyway.
Is it possible for you to consider such a change? Even as an option in game server settings.
