One might think tools like these inspired many a modernist sculptor/sculpture--hard not to see the work of Brancusi and Arp and many others (Aubock, too) in the tools themselves, and I must say that just laying them out and arranging them together delivers huge aesthetic pleasure. Most of these are brass, a couple iron, all high quality and I believe antique. Used I would guess for working with plaster, with scoops or blades/flat edges at the ends of the longer tools, and smooth, curved bottoms on the smaller handled ones. Just looking at them makes me want to make sculpt something, though I'm pretty content just picking them up and moving them around!
