16x inventory sprites, 32x+ held item sprites

this is a suggestion mostly for the existing 32x sprites of item skins, but could also apply to other currently 16x skins that could be resized.

vanilla spears make use of this mechanic and so do other mods (ie: terramity 1.0), it allows for more finer detail of weapons/tools while keeping a consistent pixel scale in the hotbar and ui.

With the addition of vanilla spears into OR later on, I hope that this can be applied to any current and future 32x toolskins, for a nicer hotbar
