Not sure if this is the best place to write this but oh well

Basically I need a good cracker, I have tried several tools and methods yet I was always unsuccessful and even caused damage some times...

I don't have a lot of experience in the area since I haven't done it for years! And as I said, the tools I have are not enough.

I'm not really asking any of you to do it for me... that would be weird...

However I'm asking you if you know a good cracking tool?

Thanks in advance and if it helps, here is a picture of what I'm trying to crack:

Spoiler:

Any recommendations?
