Sawblade

A new block crafted with a red stone block with 4 spikes/iron ingots around it like a compass. When you place it, it will have two flat faces, one of which will face you and the other the opposite direction, and 4 sharp faces. When powered from a flat face, it will start grinding, damaging mobs that go through the sharp sides as well as trapping them like a cobweb. Its flat sides are just walls. It can also shred through blocks like stone, ores, and anything weaker, either if they are pushed into its sharp face or if its sharp face is pushed into them. If you want to attach it to a slime block, you must put the slime block on a flat face. Good for making both traps and block mining machines
