If I lose it, I lose it. I don't lose my knives, and if I ever do, I'll just accept it and replace it. I normally carry one of Kershaw's budget line(OSO Sweet, Kuro, Clash, or the Half Ton) or Spyderco Tenacious, and since none of those knives are more than $35, I'm not too worried about losing them. Personally I hate engraving, and I'd rather pay $35 to NOT have to worry about sullying my knife with engraving.
