After reading the post that was given as a link, I got interested in this knife and ordered one from my local knife store. I took it on a wade fishing trip to the Louisiana cost a few weeks ago and carried it in salt water. While I only cut some fishing line and some food back at our lodging the knife worked very well. I washed it in clean water after getting out of the Gulf of Mexico and had no problem with rusting. I have found that Victorinox knives hold up very well to salt water environments.
I really like the knife but I do have a few things that I do not care for. First, it is a bit heavy in the pocket. It would work well in a nylon sheath or clipped to a belt loop. The other thing that I will probably fix myself is that the opening hole has been smoothed inside a bit which makes it somewhat hard to keep you thumb in while opening one handed. Taking a file or Dremel tool to the inside of the hole and making it a bit more 90 degrees would help making opening a bit surer.
I have had a Rucksack and the wood saw is one of the best you can find if you have a need for such a thing. I have used mine to cut a hole in the back of an inexpensive entertainment center to run electronic wires through with great results.
The main blade isn't serrated enough to be a bother. Prior to ordering my Trailmaster I went to my local store and looked at another model, can't remember the name but it had blue scales, with the same serrated pattern. The serrations are so small and shallow as not to be a bother but they do work well cutting meat, which I usede it for in our camp.
The knife also has a lock on the large screwdriver, this is a great benefit to keed the screwdriver from closing on your finger if you put too much pressure on it. It wouldn't cut you but I would pinch the fire out of your finger without the lock. Nice touch.
The can opener also works, the camp didn't have a can opener so out came the Trailmaster to open the Pork-n-Beans.
Hope this helps. If you want to know anything else, feel free to ask.
