There is quite a story behind those.
A long time ago in a russian pixel community far far away some guy did a critique another guy's piece, making a rework along the way.
After 150 comments of holywar, a few other artists, including myself, made another few reworks of that hammer and named it "green hammer burning with a righteous blue flame". It even became some kind of flashmob in russian pixel community - to draw that hammer.
After a while, when I was at country-side, I somehow stumbled upon our family shed with instruments. Being inspired by the glorious tools there, I decided to make another few icons, being:
- Handsaw woven from pure acid
- Former wood chopper, that changed his ideology and nowadays protecting nature and making publical speeches against deforestation of South America
- Red crowbar of hope for the bright future
- Personal jade screwdriver of the emperor himself
There were also Fallen pliers and Purple chthonic chainsaw, but my neighbours took them to fix their porch.
