Victorinox normally uses X55CrMo14 in their blades. This is highly stainless and reasonably tough. With only 0.52 % carbon, it will not hold an edge for any length of time. I have not seen HRC figures for this, but the low 50s would be about the best expected. This is not a steel that I would want in an EDC unless I was going to meet with a TSA agent on my way to the plane. If you add $15 to the price of the most expensive, that amount will get you a Leatherman Skeletool. This has a blade of 420HC. I don't know if Leatherman does 420HC as well as Buck, but my Leatherman blades have served me well. I have a rather ancient Swiss Army Knife. (I also have what someone told me was a French Army Knife. I bot it at a flea market. The corkscrew works well, but I have had no use for the small white flag that folds out opposite from the corkscrew.) My SAK has been relegated to EDLID status because of several Leathermans that I own. If I collected these, I am sure that I would buy one. I find it attractive.
