pricker

We tromped through woods, pushing our way around thick shrubs and stepping over pricker bushes.

I stick the tip of the loppers into the pricker canes.

It would take several expeditions before I found it, perhaps because it was half-overgrown with pricker bush, weeds and small trees.

If the latter happens, it should be at once cut back with the65 pricker, which is also used to test the thickness of the sides and base.

In his hand he holds a small "push," pressure on which by his fingers operates a minute pricker, which acts upon a moving strip of paper.
