Hi there

I'm planning on spending the considerable amount of money to purchase a multi-tool. I'm trying to conduct some research (mostly on the net) about price, features, size, etc. and cannot find some critical (according to me) information concernind these tools. I was playing around with an old Swiss Army Knife when I realised that it was extremely frustrating to open (access) and close the tools. Some were reaching the finger-nail-breaking limit!

I am considering getting one of the following:
1. Swisstool Spirit
2. Leatherman New Wave
3. Leatherman Juice (one with a saw)

Here's what I'm hoping you could help me with - which one of these is the easiest to open? I'm not talking "sissy" easy, I just want to keep my finger nails intact.

Thanks,
Naseem.
