Oooh, I thought vanilla tools were replaced because stone pickaxes have the (awful) GT durability (unless I'm mistaken about that too), but maybe it's not just a full replacement but just a balance adjustment.
Thank you for the script, I'll try asap.
EDIT: Works like a charm, and now I can indeed place torches with my stone pickaxes. Maybe there should be a section on that topic on the wiki, to avoid any (false) inconsistencies...
Does this also explain the durability discrepancy between Flint&Steel (made with Steel Nugget) vs Damascus Steel Flint&Tinder ?
EDIT: Are there other replacements that I/we should be aware of ?
