I was in that situation twice.
On a family trip Dad had limited me to 2 knives. At a cookout the only steel knife available was the serving knife that was siting next to the platter of steaks. So I pulled out my 50/50 Spydercard, which worked just fine as I watched in amusement as others used the serving knife to cut up their steak before going to sit down. Despite being nonsserrated, the thin wharncliff tip and edge of toothy Aus-8 steel it worked like a dream. To my suprise, it did not slit through the plastic plate. This was because point itself was slightly dull.
For my last birthday the family went to Outback Steakhouse where I had a T-Bone. As you may have noticed, the tips of resturant steak knives are blunt and rounded. Having forseen this possibility I decided my duplicate serrated Massad Ayoob (I have two, the early production slick almite, and a late production matte, grippier one).
The provided "steak knife" (in name only) was unable to make the cut so I pulled out the Ayoob. Dad Did not like this at all and made me put it away. I got the last laugh however: I was only able to finish half of the 20 oz monster and brought it home in a doggy bag. In the privacy of my apartment I finished the job with the Massad Ayoob.
It worked almost too well, allowing me to cut some of the connective tissue away from the bone, along with the muscle! The canted blade is more ergonomic than a traditionl inline handle as you do not have allows you to hold your hand at an odd angle. The belly of the blade was perfectly alighned, while only the easily resharpened tips of the serrations contacted the blade contacted the plate after slicing - not sawing - through the steak. The kissaki (Japanese for area where edge curves up to meet the spine) cut right to the corner of the T of course!
Lastly, if you want some rustic charm combined with thin blade performance, Opinels are easy to resharpen. Opinel even has a Laguoile-ish folding steak knife line with handles in a variety of woods and stainless Blade lengths from three to Six(!) inches.
