Initial thoughts were towards blades of at least 6inches length such as the Scrapper 6 for duties both urban and bush; but many a mention of the knife also needing to be an EDC got me thinking that a smaller, easier carried/concealed blade, especially around town, would make life easier in regard not been targeted as a potential threat by any concerned citizens or for law enforcement officers.

Since neither the time nor place for the knife's deployment is a known factor, continual carry is critical and as such it seems that a smaller blade length would be the way to go with it always being close to hand.

Current choices by rank of blade length are Busse's Game Warden and Cultellus, plus the Off & Heavy Duty series. The Scrap Yard Street Scrapper 4 & Busse Meaner Street are next, and final choices would be Swamp Rat's Howling Rat & Howling Fat at 4.5inches.

The best survival knife is the one you are carrying at the time of need, rather than the best designed survival knife left somewhere else because its difficult to tote around.
