Hi there! No worries, there are still standard dinner knives around at restaurants and the like that can be filched in a pinch.

The resort does not sell weapons (no sword store, for example) but there are ways to acquire small ones on the down-low in seedier locations at player discretion. You can read about that under locations. A brief summary: they are not totally absent but there are currently no significant weapons like grandiose spears, rifles, dynamite, etc. This will likely change as players gather reward points and contraband comes more into play.
