Fallout 4 weapons

Unlike previous installments, in Fallout 4, weapons fall under three classifications: Normal, Legendary, and Unique. Normal weapons have no special statistics on them whatsoever. Legendary weapons come with random bonuses applied to them, and are only dropped by Legendary Enemies. Unique weapons are weapons that are already named and will always retain the same special bonus. Uniques are typically either bought off of merchants or quest rewards. Normal and Legendary weapons will change their name when mods are applied. Unique weapons will not.

All stats are given with standard weapon modifications. Values in parentheses are the maximum (minimum for weight and AP cost) values in class (some weapons, like the pipe pistol, become short rifles when changed from a grip to a stock weapon). Note that not all maximum values will come from the same gun - for example, maximum damage and maximum rate of fire will typically require mutually exclusive mods.

Bladed
Bladed Weapons can dismember limbs of humanoid opponents, permanently damaging the limb and disarming the target. Like all melee weapons, Bladed Weapons benefit from Big Leagues and Strength.

Blunt
Blunt Weapons tend to stagger opponents more frequently than Bladed Weapons. Like all melee weapons, Blunt Weapons benefit from Big Leagues and Strength.

Fist Weapons
Fist Weapons benefit from the Iron Fist Perk as well as from Strength.

Renaming Weapons
In Fallout 4, the player character is able to rename any weapon, including unique weapons, at any weapons workbench. Renaming weapons does not affect any weapon stats. This primarily adds a level of personalizing to weapons and can help avoid accidentally disassembling a favored weapon, but it is also possible to use certain HTML element tags for added customization. Some HTML tags that can be used are listed:
 *  italics
 * underline
 *  list (bullet-point)

To keep your crafted weapons at the top of your Pip-Boy weapon list, append a hyphen(-) or a blank space at the beginning of the name.

Note that these tags are only visible within crafting menus; the 'formatted' text will appear in the Pip-Boy.
