In reply to amaun:
PF0 has about the same pick angle as Fusion Ice.
PF1 I guess is the has about the same angle as BD Laser/Fusion.
And PF2 is more aggressive...
There's also a polish alternative, which is considerably cheaper than Krukonogi (around 25 Eur or so pick). I got those, but unfortunately did not have a change to test 'em. Not armor steel though...
