voidblades

Here's a Modrinth-ready description:

Void Mod replaces the blade and head of netherite weapons with a live end-portal void texture, as if the weapon is a window into the void itself.

Features

• Netherite Sword — the blade is replaced with a swirling end-portal effect
• Netherite Spear — the spear head glows with the void
• Mace — the flanged head reveals the void between its knobs
• Custom teal/gold hilt reskin on all three weapons
• Enchant glint applies to the handle only — the void doesn't glint, it consumes
• Works in inventory, on the ground, and in hand

How it works

Transparent pixels on each weapon's blade/head texture are replaced with real-time end-portal rendering. The handle pixels remain solid, so the grip looks physical while the business end looks like it was forged from the end itself.

Requirements

• Minecraft 1.21.11
• Fabric Loader
• Fabric API

Notes

• Only affects netherite variants
• Other players need void in the item's custom name to see the effect (you always see it on your own weapons)
