There are multi-blade whittling knives on the market, but in general there are too many compromises for serious use, so they just are not as good as we would like to hope. The Victorinox comes with a chisel, which would be helpful, and if you knew that you were not going to need any screwdrivers then making some scrapers could be useful. But I feel like at that point you are so far away from what anyone else would predict that you might as well go custom. Its a tough thought but are 10,000 other guys going to want tools just like you? I doubt it.
after seeing how well they did with the multi's, I'd certainly take that as an option, but lets not forget that a multi is always a compromise.
