Resin Hammer (An On The Go Anvil)

My idea for Minecraft is to add a use for resin. My idea would be a Resin Hammer. The Resin Hammer, would be like an anvil that you would be able to use while on the go. Like an anvil, the Resin Hammer would be able to repair your tools and armor but without the need to have to carry around an anvil and have to place it on the ground to use it. Unlike a grindstone, if your repair an enchanted item it won't take away the item's enchantment. When you repair an item with the Resin Hammer it would not take away XP levels, but would repair your items less then an anvil would. For balancing, the Resin Hammer would have a low durability, but you would be able to apply Unbreaking to it. I would imagine the Resin Hammer has a similar durability as the Brush when you use it to get Armadillo Scutes. You wouldn't be able to put mending on the Resin Hammer. This is to make it so the Resin Hammer isn't to overpowered. I believe this would be an excellent addition to Minecraft, because it would use preexisting materials from the game which don't have a use, and add a very useful mechanic for players. I also think this is a good idea because it adds some real world elements but twist them in a classic Minecraft fantastical way. In the real world, natural resin is used for some repairs. Not to the extent of metal, but that's where the fantasy element comes in. Also, players have wanted hammers in the game for some time, I think this would be a good way to implement what some have asked for.
