Iron Trap

Although the iron trap has a drop, no vanilla tool is suitable for breaking it, so breaking it with any tool will have no effect. Furthermore, attempting to use Attack / Mine to order a tool to mine it will not happen, as tools only mine blocks that they can break.

However, it is still possible to make an iron trap block drop a living iron trap with an explosion.

Using cheats, it's possible to create a tool capable of mining it by modifying minecraft:tool.rules data component. Can be add this block in #mineable/pickaxe so that it can be mined by any pickaxe (additionally, adding a tag like #needs_iron_tool prevents it from being mined by some pickaxes.)
