Picking a Prickly Pear with the Paw
This is an intermediate textbook of the kind handed out to second year university students. Leafing through it reveals that it's aimed at are looking to broaden their understanding of harvesting. It has many diagrams and densely packed passages of text. You'd need to have a reasonable amount of knowledge before you could really hope to make much of a dent in it.
It is coloured uncoloured and is made of some unidentifiable material. It looks like you could use it to practise harvesting plants.
