By "go-to outdoor knife" what exactly do you mean?
I have a lot of SOG fixed blades and I like them all but none of them are used as a woodsy-bushcrafty-camp blade. For me, my SOGs are more utility/tactical blades. The ones I have that would be consider woodsy are collectors like the SK5 Tigershark.
Further, the blade shape on the kiku doesn't look conducive to many outdoor knife tasks. Seems like much more of a tactical blade. The Aus8 would worry me too. Not really a woods type of steel. Great for budget EDC and utility but I would much rather have a good carbon steel for wood work. For these reasons, I wouldn't get the Kiku for an out-doors blade. But my needs might be different than yours.
While the RAT 7 above looks good, if you do some research on Ontario fixed blades you will find the fit/finish and heat treat are a bit fickle. Plus, for what you would spend on the Kiku, you can do better than an Ontario (the sheath also sucks).
My recommendation, and what I use, would be an offering from Esee. I have several of their blades. My go-to outdoors knife is an Esee 6. I have an Izula, 4, 5, 6, and Junglas, but the 6 and Junglas see the most woods use. You might be tempted by the 5 but it is a bit of a gimmick as it is meant as an extreme survival tool for a downed pilot, it would be great to cut your way out of a chopper but not that great at cutting normal stuff. Take a look also at the Laser Strike, both the 6 and LS are in the size range of the Kiku but much more suited to woods work. Everything on an Esee will be upgraded compared to an Ontario fixed blade: fit/finish, steel heat treat, sheath, and warranty. Esee has the best knife warranty in the business hands down. Blade breaks for any reason, they give you a new one. Unconditional, forever, and transferable.
