Been a while. Been out dealing with some health stuff. Not sure yet if I'll be as active on the forum as I was.
Haven't done much knife-wise. I did replace stuff that was worn out/ broken/ heavier than newer stuff. Old compass/ thermometer had the thermometer fall out some time ago. Found a crack in the old Fox40 whistle. So, updated some more of the old with newer lighter more modern stuff.
Sharps - Victorinox Venture (fixed-blade, spear point, main tool), SAK Sentinel (large folder, one-handed if needed, non-serrated, no clip), SAK Excelsior (small folder, pen knife with two small very sharp blades). Truth be told, will likely never need the Venture, but I prefer using a fixed-blade over folders for camp/ emergency tasks. All IMHO and YMMV.
Spare compass/ thermometer thing I picked a few years ago. And the new very loud (110 dB ) thing.
