Speaking strictly of knives only and not any cutting tools in general, my criteria would be versatility, major types of use, environment, ease of replacement/warranty and legality:
Based on al. tho, one of the following would be my choice:
A) A 4-4.2” large stockman. 3 blades, tipically a clip point, sheepfoot ans a spey one. Versatile, useful, compact, optimal for urban living. Multiple makers, always possible to buy an affordable yet guality replacement.
or
B) a 4.5-7” fixed blade.
My choices would be:
ESEE-4 or ESEE-6 or a Becker BK-7.
Could be used for most small knife tasks, but better suited for outdoors use. Due to the grinds, they would make acceptable kitchen knives too. The ESEEs have unbeatable warranty, the Becker’s one is great too. The could be great for country living, very versatile.
What I would definitely NOT choose for this scenario is a Pakistani knife. Not worth risking to get a poorly made knife or a knife like object - that is unfortunately a very likely occurrence.
Good thing that all this is a hypothetical.
