FIGURE 1 in The challenge of hard-to-reach spaces in mechanical fossil preparation: Development of the Wada air scribe, a novel short-bodied air scribe with an adjustable handle

FIGURE 1. Usage example of a conventional pen-shaped pneumatic air scribe. A. Fossil preparation inside of the deep cavity. Note that preparators are required to hold the air scribe at an awkward angle when they try to prepare a hard-to-reach area. B. Micropreparation using the pen-shaped air scribe. The handle of the air scribe could be caught on the rim of the objective lens.
