Likewise, i use my SAK Hiker every day and whilst i've not done a camp using just the Hiker, a long while back I and a couple of then mates used to challenge ourselves to a particular task whilst and and about on a bimble, be this a bit of carving to making a fire set from what was around us and getting a fire going, i think it was due to these challenges that we all realised the potential of the humble SAK.My SAK Hiker is the one tool/camping item that has literally come on every single camping trip/hike/bimble etc. Wouldn't leave home without it. In actual fact, I keep meaning to do a bushcrafty camp with this as my one tool option to prep fire wood and make some camp implements.
I keep eye-ing up the larger SAK Forrester as a potential purchase. One day perhaps!
The toothpick and tweezers are probably the most used tools on my SAK. Handy for splinters and whatnot. I've also found a very modern use for the toothpick...it's great at cleaning out the build up of fluff and crud in mobile phone charging ports. Being plastic, it's much less likely to damage the connectors.
Also, like yourself i've been looking at the Forester and also the Trailmaster as a potential purchase for future adventures.
