I got my Tiga last weekend. Did a quick overview on my IG.

It did require a little tweaking to get it to my liking. Stripped it down, polished the PB washers, applied 10wt Nano-oil to the washers and 85wt to the detent track. The stop-pin is designed to rotate to combat wear so it had slight side-to-side play which gave a little rattle when the blade was opening. I put a little dab of blue Loctite on each side and that alleviated the issue. I should mention, the blade never had any kind of play with the rotating stop-pin. Lastly, the clip needed to be a bit tighter so I took it off and bent it to have better pocket retention. I emailed Grayman Knives about all these issues and they offered to fix them for me. I didn't feel like shipping the knife back so I took care of it all myself.
I'll admit, it is definitely not a knife for everyone. It's heavy. It's thick. It's on washers. It feels like it would be at home in a toolbox with wrenches, vicegrips, and speed-handles. I have a soft spot for this kind of thick bladed, absurdly overbuilt knife; e.g. Eutsler Equalizer, DSK DBV2, Grayman Satu, CKF Muscle, or any of Crusader Forge's offerings. There's just something satisfying about a chunk of useful metal in hand.
Just a little background, I work in Navy aviation and my command has been preparing for deployment. I've been carrying this knife for the past week as we've been transferring pallets of assets, consolidating supplies, clearing out tri-wall boxes of unused materials. It's times like this that a sharpened, folding prybar comes in very handy. In aviation every single tool has to be checked out in a log, so a simple task becomes time consuming when you just need a flathead to open the metal clips on a crate. That complication is avoided when you have something to pry with (yeah, I know most knives are purely for cutting and not prying). The sharp edge comes in very handy when there are tri-walls that need to be broken down. If you're not familiar with a tri-wall box, they are massive triple-thick cardboard boxes used to ship heavy tools and gear. After all that, I used the knife to trim a little window in some bubble wrap to view the part-number/serial-number on a piece of sensitive electronic equipment. The Tiga handled all these tasks without issue.
Could thinner-bladed knives have handled these tasks? Probably. My Spyderco Shaman is usually my go-to work knife but I would have been hesitant to pry metal clips with it. Most of my shipmates have their own pocket knives but most have the tips broken off and dulled from prying. The Tiga's blade shape and thickness gives me confidence that few other knives provide.
