GrassBlades

A really long time ago somebody on the FTB forums asked for a mod to prevent weapons from breaking redstone and tall grass.

I made one, but then never uploaded it to Curseforge.

So it's sort of a Modrinth-exclusive mod? For 1.7.10???

Sneaking disables the effect.

This mod is kinda dumb, you don't actually swing through grass, it just makes insta-breakable blocks unbreakable if you're holding a sword.
