With regards to the "Officer's" sgean dhu with small tools folding out of the handle, I have seen them offered. The blurb I've seen said they were based upon a style worn during the First World War.

As to the utility of the sgean dhu, I think it depends upon the particular knife. My own is made of pretty fair stainless steel. It's not the equal of a modern knife steel, but as good as most ordinary 19th century knives. It works fine for anything you'd use a spear-point utility knife for. I keep mine sharpened (it holds an edge moderately well, though it's not great that way) and I've used it to cut cardboard when fashioning a slotted box for filled-in forms at the highland games, for making a fuzz stick to light off the barby at same (my wife doesn't like to use charcoal lighter, she's a purist about outdoor cooking), cutting lengths of line, and many similar tasks. It's no better than a folder of equal size would be, really not quite as good, but it does the job and that's one less thing I have to cram into my sporran or clip to my belt. And I'm going to be carrying the sgian dhu anyway. ISTR that Matt Newsome has mentioned using his as a box cutter.
