I must admit that Deforest, not I, who created what we call the “Hooked Diamond.” So I still enjoyed correcting some design details in an apparent knock off I found to create our “Hook Diamond-BULL-NH.”
Below are reviewer comments:
Locks picked: Medeco Biaxial (!), Abus 71/40, Abus 55/40, Master 140, and Master 141
Impressions: Wow! What a fantastic pick. It seems to have a bit more material on the cusp between the tip and shaft than another design. I mostly used it to attack locks with very open keyways, but it did a fantastic job with them! I even managed to get a Medeco biaxial picked with it. In my experience, these types of picks would be great for picking high security locks with counter-milling, though I haven’t tried it specifically with this Shrike pick. It appears to be a great complement to the Peterson gem—the tip profile is similar, but the profile is deeper.
