This article is about the origins of how some fighters trained themselves to use simple weapons to beat other fighters in their fights. Yes, it's a simple weapon used to beat opponents. A regular, non-lethal, punching knife 5e blade is connected to a straight, flat handle that extends from the forearm to the base of the fist. A skilled fighter is reckoned to be capable of using almost any weapon at hand, whether it be a club mace, stick, sword or any other.
Some people would wonder what the big deal is about some people training themselves to use simple weapons 5e as a form of self-defense. They say if you are not going to do something that may potentially get you hurt then why bother with all that? Well, there are good reasons for such training and practice. Here are a few examples of what I'm talking about.
Each of us can benefit from knowing what constitutes a valid weapon or what we should stay away from based upon our own needs and personality type. If you're a street fighter type of person then you should definitely stay away from using handguns of any kind, including fully automatic ones. You see, handguns fall into the category of both melee and ranged weapons. While a street fighter would likely use a mace or stick for the occasional fight, a thief would probably use some sort of concealed weapon or instrument of some sort, such as brass knuckles, or a baton. Knuckles, bars, batons and so on all fall into the category of melee weapons or, more specifically, weapons that deal "slashing or thrusting damage".
As a side note, this also includes every single kind of ammunition you can think of and more. For example, every shotgun, every rifle, and every pistol that are not specifically intended for hunting, are categorized as either melee or ranged weaponry. This is so that it is clear that you should always treat every weapon as if it were a melee weapon or ranged weapon, even if it is meant for the wrong use! It is very easy to lose sight of this and shoot yourself in the foot while playing this game.
Each weapon has it's own classification as listed above. A quick look through my dnd 5e martial weapons guide should give you a good idea of what type of weapon you are looking at. For example, a finesse weapon is one that deals piercing damage, such as a dagger or a bow and arrow. A finesse weapon either deals slashing or piercing damage, depending upon which edge of the blade it falls on. While light weapon deals extra damage on a hit or a miss, it doesn't have an offensive capability and is usually used to block, parry, and/or disarm opponents.
If you attempt to use a weapon in this game that is not classified as a finesse weapon you must reload before using it, or throw it away. However, some actions can still be performed while loaded or unloaded. When making an attack with a finesse weapon, you can use your strength or dexterity modifiers for the attack and damage rolls. You must use the same modifiers for both the attack roll and the damage roll. You can use one of your stronger attacks to fill in gaps in between your other attacks. You can also move between attacks using your weaker attacks as long as you do not miss.
Your throwing or grappling attacks are considered to be one-handed weapons for the purpose of determining damage. If you have more specialized training to use them than your simple weapons, they count as one-handed for the purpose of determining attack rolls. All your finesse weapons are considered to be one-handed when using them to attack. The exceptions are the spear, axe, sword, and quarterstaff.
A ranged weapon used to attack a target at a distance can be used with one or more finesse weapons for the purpose of improving your ranged weapon damage by leaps and bounds. You have to make two attack rolls for each ranged weapon used in this case. Once you have the number of ranged weapon attacks you have used, the DCs for all your ranged weapon attacks are calculated. Each weapon has its own individual DC so you cannot use one that already has a higher DC for comparison.
