Open any canned food with short and long-bladed weapon (even modded) or stone.
No more need to carry a heavy can opener.

• Short blades (e.g. knives), long blades (e.g. machetes), stone can be used to open canned food in addition to a can opener.
  
• Weapon might lose condition upon opening a can.
  
• Your character might get injured.
  
• Opened can will be poisonous if opened with bloody weapon or bloody hands (if used a stone).
  
• Some food might be spilled.
  
• Time required to open a can depends on a type of opener used.

Vanilla can opener and stone are always available. If you use a can opener everything will be like in vanilla.
Short blades become available if your character has Strength level 3.
Long blades become available if your character has Strength level 7.
*Only weapons with the "CutPlant" tag can be used as openers.

A chance to break your weapon depends on a weapon's durability, character's Maintenance and Short Blade or Long Blade skill. It's the same as a vanilla chance when attacking zombies.

For example:
Hunting Knife, Short Blade level 0, Maintenance level 0: 10% chance.
Kitchen Knife, Short Blade level 3, Maintenance level 2: 25% chance.
Machete, Long Blade level 2, Maintenance level 4: 5% chance.

A chance to get an injury depends on the following stats.

Increases chance:
- Panic, Drunkenness - greatly increases an injury chance
- Fatigue, Hypothermia
- Clumsy trait

Decreases chance:
- Short Blade or Long Blade skill (except when used a stone)
- Can opening experience (more cans you open less chance)
- Hunter or Former Scout traits (one of them, effect doesn't stack)

Your character might get a scratch or a deep wound on left or right hand. The more damage a weapon can do, the greater the chance of serious injury.

The more blood on your weapon (on character's hands if used a stone), the more poisonous food will be (won't kill if your character is healthy).
Wash your weapon or hands before use!

Opened can will contain less food depending on a type of used opener, can opening experience, Panic stat.
Short blade: min 0% spilled, max 15%.
Long blade: min 5%, max 30%.
Stone: min 10%, max 50%.
