Your huntsman should do well in a survival situation. The saw gives it a very powerful tool. With that saw, you can make a good debris shelter, split firewood, and make those bushcrafty things that the survival crowd is so fond of. I wouldn't feel too bad about being stuck in the boonies with a sak that had a saw blade on it. The steel is just soft enough that sharpening it is a fast easy thing to do. And if you are in a situation where the wood is wet, take that saw blade and saw halfway down through the wood, then turn the wood to where the saw cut is facing down and slam the wood on the ground or against a tree. The wood will split along the grain, and you just pull it apart. There's lots of videos on U tube about splitting wood with a saw. Take a look at them. It's finesse over brawn, and at my senior citizen age I'll take it. Your huntsman will saw down a sappling with ease, sharpen it, and then you fire harden it, and you'll have a spear similar to what Neanderthal man used to kill his food.
Contrary to what the die hard survival crowd thinks, you do not need multible bowie size knives and an ax to survive. Some knowledge and common sense go a very long way. A few tools will help. Like most things, the gear does not make the man, you have to know what you are doing. Most people would be surprised at how little you need.
I've been interested in survival for most of my life, and while in the army took the course where they drop you off for three days with just a few items including the standard issue MLK scout type knife. It did fine. But the thing is, in the past 50 some years I've researched the subject, I've found that time and time again, people survived with some pretty mundane gear. Their mindset made the difference. Software over hardware.
Some geographic areas may require something unique to the area, like a machete in the tropics, but in general a sak huntsman will nicely as a pocket survival tool that is almost always with you. And that's the big thing right there; the stuff you have right there with you, in your pockets, everyday.
