I'm glad you like it and happy new year to you as well!
The saw blade is mostly an edited music disc! The very small circle in the center is from the iron block.
The block portion is made from smooth stone, crafting table, bookshelf bottom, dispenser vertical top, and a minecart rail. The bottom is strait up just oak planks like the crafting bench so you could potentially hide it in a low oak ceiling and still access it.
