Just another Hook 3 pick, but this one has a narrower height on the shank. You will find that this greatly improves your egress with 0.025 thick picks.
Locks picked: Abus 72/40, Kwikset mortise cylinder, GMS SC1 mortise cylinder, and a Y1 Euro cylinder.
Impressions: Seems to be based off the hook 3, so I’ll include my thoughts on the traditional hook 3 as well as the new prototype: I absolutely LOVE this profile, though for some reason, I may be the exception. It is the only pick that I own that has allowed me to pick my Abus 72/40, and I rely on it for Schlage C1 locks, too. I have an Original Medeco with a very low cut in chamber #5, and the hook 3 is the only Peterson pick that can get underneath that pin without over-setting it.
