decorated weapons/tools

similarly as armor trims, adding little of customization for tools and weapons would be nice, especially as with those we could color-code different enchantment combinations for practical uses (silktouch/fortune pickaxe or smite/sharpness swords for example) or color-match detail on weapon with our armor with trims

I imagine something simple since it is hard to make many trims for weapons/tools, so something as just gem placed on part of tool/weapon and handle customization, two should be possible to apply together too
weapon/tool "trims" could come with gems of few shapes, like "round" or more rectangular, same materials as armor trims, sword could have it in middle of sword guard where it meets blade, spear just behind spear head, pickaxe at place where pickaxe head meets handle, trident behind part it "forks", and so on

handle customization would take part netherite tools have differently colored from other tools and recolor that with its own, separated selection of materials (netherite tools wouldnt have this differently colored from other tools anymore), items could be stuff as string for white/light gray, leather for brown, bunny hide for light brown, metal ingots for their corresponding colors and so on, it could give little touch people could add to their tools too if desired

handle customization could be also applied on bows and crossbows, all with same "handle" or "tool/weapon" trim item, just parts those would get recolor on those would need to be figured out
