Peterson adapted another company’s design to theirs, correcting weaknesses in the design. They also adjusted the curves of the picks to make some more functional.

The end result is similar – but not identical – and it seems to work MUCH better according to the reviews…..

Below are reviews from other lockpickers. In English, as they were written in the original and roughly translated:

Locks Picked: Master 141, master 3, a few cheap wafer locks, Sentry Safe lock box, and Y1 Euro cylinder. Master 570 to a shallow false set.

Impressions: I love it! In the past, I haven’t had a lot of luck with traditional raking, though I’ve “rocked” city and Bogota-style rakes with good results. This is the only rake that I’ve had success using in the traditional sense (moving the pick in and out of the lock rather than rocking). It made short work of several wafer locks and master 3s, and was quite comfortable to use. I noticed that the profile is nearly identical to 3/5 of the sine quint wonder/wicked wave. I don’t keep rakes in my main picking set (I only ever SPP), but I will make an exception for this pick!

This is the only rake I have used successfully (getting the pick in and out of the slot instead of rocking).
