Need help from Ping experts re Ping Eye 2

Hello - thinking of buying this L wedge and a matching SW.

Trying to determine if this is a model that has “U-shaped” grooves. The writing is in the right direction (rightside up when in the bag) - but it only says “â€Karsten”†not “â€Karsten Mfgâ€.”

Are these markings correct?

Thanks in advance

Here is the info that has been posted before:

I believe the version with "Others Pend." is the one that spun the ball the most. If you ever see the face of one of these wedges, the grooves look much wider than subsequent versions.

Some of the old Ping wedges for sale look like they've been dragged down a gravel road (likely from a lot of bunker shots or hitting sandy range balls). Even if the face looks clean, often times the grooves are still worn down quite a bit and the performance isn't great (I have a lot of old Ping wedges lying around and they all look fine, but I'm pretty sure the grooves are quite worn on some of them based on how the ball reacts at times).

If you want to get a set because these wedges are "cool," I'd say that's fine. However, if you think they are going to work better than anything new you may be disappointed.

Huge help - thank you. I had one of these before, and just thought it might be cool to check out.
