Bushcraft knives are generally selected for carving, wood preparation and campcraft. Survival knives are often marketed for broader outdoor utility. Their functions overlap, so compare actual design and intended use.
It depends on your activities. Compact knives may suit food preparation and light cutting; a fixed blade may be useful for more demanding campcraft. Prioritise appropriate size, grip and maintenance.
A full-tang knife has blade steel extending through the handle. It can support structural strength, but durability also depends on blade geometry, steel and manufacturing quality.
Stainless steel generally offers better corrosion resistance. Carbon steel often needs more care to prevent rust. Neither category is universally better: performance varies with the steel and heat treatment.
Knife laws differ by state and territory, and restrictions may depend on knife type, location and purpose. Check current official rules for your jurisdiction before buying, transporting or carrying a knife.
