It's the paradox of using a knife: you like the pattern, love carrying it, thrilled to use it as it gives pride of ownership but there's a very real inherent danger of losing it sooner or later.
But, at least it's been used and enjoyed and not hidden away uselessly
In an ideal world, where's that? you could buy duplicates of knives for this reason but that very seldom happens.
The Lionsteel suggestion is I think, very good. Excellently made, very durable using non corrosive materials and not too heavy in the pocket either. You could 'downgrade' and use a slim SAK with openers, very decent knives but not so individual obviously.
I lost a very good paring knife that must've got mixed up with peelings and papers in the rubbish. A small Fontenille-Pataud Laguiole I bought from the Exchange (from France to USA to Europe again) got put in a DISHWASHER by a visiting GF (these non knife types....) and the Walnut scales were totally -ed. Sent it back to FP for an expensive rehandle in horntip, liked it a lot. Then it got lost on some boring and useless business trip in an hotel, clearly I was not meant to have the knife
If a treasured knife gets lost, let's hope it's found by a knife-type and goes on having an appreciated life
