Shears made by copper instead iron

Until now (20w51a) the use of copper is strictly reserved for the crafting of unique and multipurpose tools, such as the spyglass and the upcoming brush; so I propose to give the possibility to craft the shears with copper instead of iron. After all, iron has the ability to create as many useful items as copper (hopper, pistons, flint and steel etc.), so I don't see the problem of "allowing" the crafting of copper shears.
