Does that mini grip lock up tightly when open?
The 530 is pretty cool and insanely lightweight. I had one for a little while. On the flip side, it is a THIN blade, and I have some serious doubt whether it could take much abuse at all.
So far, my favorite folder by far is the CRKT Otanashi Noh Ken (ONK). It's not a folder I'd use for any utility stuff, but mainly just defensive use. If you have to use a folder, it's pretty damn large, intimidating, with a blade profile that offers a great deal of penetration and slashing ability. I love this thing
