to dig a hole, for planting a small tree. This is the tool. You kneel or squat. After a while, end up sitting. Feel with your fingers and find the perimeter by fingertip. Then, this tool. Moves down along the edge and over time creates enough of a gap that the Rocks are loosened and can be lifted out by hand. For this one, i filled the hole with water and will wait till tomorrow to try again. Once it's out, i think i can plant the Fig. This is the third day i worked on this hole.
tilting the paper just a little...in morning Sun....the graphite looks like silver.
"graphite pencils produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging." wikipedia
and with kneadable erasers, you can just press, just firmly, and lift the mark away, layer by layer, particles by particles.
graphite is Magic.
