Just another Hook 1, but this one has a narrower shank height. You will find that this greatly improves your egress with 0.025 thick picks. Below are reviewer’s comments:
Locks Picked: GMS SC1 mortise cylinder, Kwikset mortise cylinder, and Y1 Euro cylinder. Impressions: This may be the short hook that Peterson is missing! It seems to be based off the Sparrows Tron, but has a bit more material on the cusp between the tip and shaft. The profile is similar to the Peterson hook 3, but has a narrower shaft and a smaller tip, both of which are welcomed changes. I would include this profile in my kit as my “go to” short hook.
