Knife

For the uncraftable jade variant, see jade knife.

The knife is a primitive melee weapon, it that does a low amount of damage, has a short cooldown, and deals sharp damage. As is typical with any sharp weapon, knife attacks cause bleeding, and generally fares poorly against armor when compared to blunt weapons. Due to its low cooldown, knives are skill-friendly weapons; even if a pawn equipped with a knife misses their attack, another attack will follow not long after.

Acquisition

Knives can be crafted at the crafting spot, fueled smithy or smithy with 30 Stuff (Metallic) and 1,800 ticks (30 secs) of work. It can also be purchased from any outlander and orbital combat suppliers, or obtained from outlander and pirate raiders drops.

Analysis

Knives are low-tier melee weapons with a slightly below average damage output, but are cheap and fast to produce. The fact that you can make knives at a crafting spot makes this weapon very desirable in the early game, especially in hard scenarios, like Naked Brutality. If you have no decent crafter, the knife is a good option, as no weapon will be high-quality and you will level up a crafter more quickly.

That being said, the gladius offers significantly better performance for little more in the way of resource costs and more time to craft. When you have a colonist with good crafting skill (crafting level > 7 or so) and can build a fueled smithy or electric smithy, then this is the moment to upgrade to the gladius or Longsword, and have a good chance to produce excellent or better quality weapons.

A plasteel knife* can be as good as a steel longsword (of roughly equivalent quality), dealing less damage per hit but with less cooldown between attacks. Overall this yields a little more DPS but with lower penetration, making it good in the early game against "softer" (unarmored) targets and for colonists with low melee skill but great potential (e.g. skill < 6 but with passion in melee, and/or the brawler trait. (Or for those with a low shooting skill with no passion, and so little prospect to improve there).

(* like the normal-quality one start your three colonists start with if you crashlanded)

Against armor, a knife actually performs slightly better than its gladius counterpart, probably owing to the shorter cooldown. That being said, a stone club still performs considerably better than either. When talking about plasteel, the knife continues to outperform its steel gladius equivalent, but the steel club is still better here.
