I've always preferred manual folders. The fact that this AO folder has a manual detent allowing it to be "de-assisted" is fantastic. I've had 2 Blurs and removed the torsion bars on both. Tighten the pivot up tight, rock solid lockup, opens easy.
Had my ZT 0301 de-assisted as well. Sent it off to a friend of mine to drill a small divot for the detent ball to fall into when closed. Love it.
