  The Bloch point is a point singularity in the magnetisation configuration,
where the magnetisation vanishes. It can exist as an equilibrium configuration
and plays an important role in many magnetisation reversal processes. In the
present work, we focus on manipulating Bloch points in a system that can host
stable Bloch points - a two-layer FeGe nanostrip with opposite chirality of the
two layers. We drive Bloch points using spin-transfer torques and find that
Bloch points can move collectively without any Hall effect and report that
Bloch points are repelled from the sample boundaries and each other. We study
pinning of Bloch points at wedge-shaped constrictions (notches) in the
nanostrip and demonstrate that arrays of Bloch points can be moved past a
series of notches in a controlled manner by applying consecutive current pulses
of different strength. Finally, we simulate a T-shaped geometry and demonstrate
that a Bloch point can be moved along different paths by applying current
between suitable strip ends.
