Wait for my Randall #14 O1 = about 30 seconds. Walk into the bedroom and pull it out of the box. For a Busse with Infi, not at all, bought a Camp Tramp because I learned that the expensive Randall just doesn't get used.
To do over, I would get a Ranger, RAT, or whatever in 1095 or L6 and G10 slabs. One thing a hard use knife for survival use needs is to make sparks on a Swedish fire steel, and not all stainless knives do that well. Further, an expensive stainless doesn't offer a huge performance benefit compared to a good high carbon steel. It in fact may be tempered too hard, have a brittle edge, be prone to breakage at tip or tang, and it's harder to replace if lost. Carbon steel knives are easier to differential temper, cost less, and are easier to keep subdued - carbon steel ages to a naturally dark patina.
Rust? Leather sheaths and a complete failure to maintain equipment in the field are both user faults. Don't use leather, period, and don't fail to keep the blade dry and oiled. It's a requirement in the field. Frankly, stainless knives were originally sold to lazy civilians for their pocket knives. The market got tired of watching blades tarnish and wanted shiny bling. If you're really using a field knife, it won't have time to get rusty, and won't keep a nice finish anyway.
The money saved on not spending it on a macho collector's show off knife can go toward better things like water purifiers and serious outdoor clothing. Frankly, I put it toward better use buying propane camping gear to use in the house for emergencies, car repairs, etc.
