Pretty well instantaneous but there is a little oscillation as the spring settles out right after the slam. But I think it will be well clear of the material ... hope so. Might need to figure a way to dampen it without affecting the recoil speed.  ::) Its a bit worse when vertical.

How about using two springs with different spring rates, to minimise bounce?

With teh hammer approach using inertial weight you will not have NEAR the cutter power as a levered (bolt cutter style) cutter. There are bascially only 2 methods to improve the cutting power of a hammer. 

Increase the speed of the hammer  ( larger air intake at the cylinder(more, faster flow) and a LARGE OPEN exhaust port area)

Increase the weight of the hammer ( not always the better choice )

Just make sure you keep your pinky away from that area.
