Yes, W1. And it's not cutting, it's inserting.

They aren't labeled, which does not help!
With the board component face up, and the contact fingers at the bottome, W1
is to the right of E69, and W2 is to the right of E73.

Of the 4 known sets of drawings for the -11/05, 3 are available online. This
page:
http://gunkies.org/wiki/PDP-11/05
gives the names, which should help you locate them (all are in BitSavers,
IIRC).
