"V" notch in hooks

[Buzo]

I recently purchsed an inexpensive pick set that included a hook with a "V" notched into it and I was wondering if there was a specific reason for this hook vs. The normal flat edge hook. I did something similar with my home made hooks and I do like the feel of the notch, but I was just wondering if it was desingned specifically for one type of lock ie: wafer locks.

I've heard that they are great for rotating the pins in Medeco locks.

I saw someone post a picture of one here, and thought it was a good idea - so I made one, but I honestly haven't used it much.

I thought it would help me 'stay on the pin', but I found that I didn't really need help with that. I can see how it might be useful for wafers though.

I would also think it's designed for "staying on the tumbler", but depending on the shape of the "V" that works well only with specific tumbler/profile shapes, like a wafer with a sharp edge, or a pin with a quite pointy tip in a straight thin profile that guides the hook exactly on the tip of the pin.

It helped me when I was first learning to spp but I find I can use a flat edge just as easily now. As for medeco, I don't have much experience with them. I've picked 3 different 5 pin medeco locks but I used a half diamond to push/pull until the sidebar set then spp'd them. Never tried the notched pick for them... I will have to try that...
