StoneBlade
by KlooDoh
StoneBlade makes stonecutters damage only adult mobs that walk over them, leaving baby mobs untouched.
What it does
A stonecutter placed in the world now strikes any adult mob that stands on it and drains its health. Baby animals and baby zombies take no damage, so a player crafting or breeding near a stonecutter will not cause accidental deaths of young mobs. Existing breeder setups and baby chicken pens keep working as they did before.
The mod suits a mob farm built around a hopper: a stonecutter placed above the hopper turns the walkway into a simple kill point for chickens, cows, creepers, skeletons and iron golems once they grow up. It is meant as a small gameplay tweak rather than a full redesign, so established grinder designs can stay in place and the mod does not replace them.
StoneBlade is published for Fabric and NeoForge, with files for 1.21.11 only. Either side can run it, and neither needs it. The code is not open source; the author keeps all rights reserved.
Key features
Adult-only damage
Only adult mobs standing on a stonecutter lose health, while babies on the same block are unaffected.
Safe baby mobs
Baby animals and baby zombies are never hurt, so breeding and raising young mobs stays safe near stonecutters.
Simple hopper farm
A stonecutter above a hopper gives a quick mob farm that needs no elaborate lava or kill chamber build.
Existing farms keep working
Breeder setups and baby chicken pens continue to function, and the mod does not break established grinder flows.

Use cases
Hopper mob farm
Players place a stonecutter above a hopper so grown chickens, cows, creepers and iron golems that walk across it are harmed and drop items into the hopper.
Protected breeding area
Players keep a stonecutter walkway beside a baby chicken pen, where young mobs cross the same block without being hurt.
Who it’s for: Players who want a light mob farm built on a stonecutter, and players who breed or raise baby animals and want to keep them safe from accidental damage.

What the author says
StoneBlade is a gameplay tweak that finally gives the stonecutter the respect it deserves. Instead of building elaborate lava blades or awkward kill chambers, you can simply let adult mobs walk over your workshop tools and watch the stonecutter quietly do its job. This mod makes ONLY adult mobs take damage when they…
