Extendomerald
Extendomerald lets players craft emerald tools by turning emerald shards into a clump, hardening it in a blast furnace and sharpening it at a stonecutter.
What it does
Players combine four Emerald Shards at a crafting table to get an Emerald Clump. A blast furnace hardens the clump into Hardened Emerald, and a stonecutter sharpens that into Sharpened Emerald, which is the material for the finished tools. The mod is built for players who want a gem-based gear tier that vanilla Minecraft does not include, and the author notes that Mojang never added emerald tools.
The tool set covers a sword, bow, pickaxe, axe, shovel and hoe. The Emerald Tools have an ability: when the player crouches, a 3x3 area is mined at once. The mod runs on Fabric for 1.21.4 only, and it is open source under the CC0 1.0 Universal license, with the source code publicly available. Client and server both need it, so players and the server must install the same build.

Have you ever wondered why Mojang didn't add Emerald tools? Emerald Tools have the ability to mine in a 3x3 area if you crouch.
