None of the blocks appear to have a defined tool to break them, while the ones based on wood can be broken by hand they do not gain a benefit in break speed by using an axe. Regardless, they DO drop an item when broken.
on the other end, any of them that are based off stone materials like the furnaces or the smoker: cannot be retrieved once placed. A pickaxe will not break them quicker, meaning they're mined at a snails pace, and they do not drop an item once broken.
