Before today, I had only gotten the 140 twice. I was practicing on a Master 141 and 142 today, and thought I'd give the 140 another shot, and I ended up getting it twice with a snake and once with a half hook, all in under 3 minutes at most.
The first time I got it with my snake pick, all the pins except the first were set, the first pin is serrated and I just used the tip of the snake pick to bring it down and the plug turned!
For anyone else having trouble with it, just keep practicing, that's how I was able to open it. Try different ways, even if they seem odd.
I was once told, to "destory a scientif in a Fenrir".
I have since then looked at life differently.
