Black powder can be prepared in a simple, safe manner. It may be used as blasting or gun powder.
MATERIAL REQUIRED:
Potassium nitrate, granulated, 3 cups (3/4 liter) (see Sect. I, No. 2)
Wood charcoal, powdered, 2 cups (1/2 liter)
Alcohol, 5 pints (2-1/2 liters) (whiskey, rubbing alcohol, etc.)
Water, 3 cups (3/4 liter)
Sulfur, powdered, 1/2 cup (1/8 liter) 2 Buckets each 2 gallon (7-1/2 liters) capacity, at least one of which is heat resistant (metal, ceramic, etc.) Flat window screening, at least 1 foot (30 cm) square
Heat source
Large wooden stick
Cloth, at least 2 feet (60 cm) square
1. Place alcohol in one of the buckets.
2. Place potassium nitrate, charcoal, and sulfur in the heat resistant bucket. Add 1 cup water and mix thoroughly with wooden stick until all ingredients are dissolved.
3. Add remaining water (2 cups) to mixture. Place bucket on heat source and stir until small bubbles begin to form.
4. Remove bucket from heat and pour mixture into alcohol while stirring vigorously.
5. Let alcohol mixture stand about 5 minutes. Strain mixture through cloth to obtain black powder. Discard liquid. Wrap cloth around black powder and squeexe to remove all excess liquid.
6. Place screening over dry bucket. Place workable amount of damp powder on screen and granulate by rubbing solid through screen.
7. Spread granulated black powder on flat dry surface so that layer about 1/2 inch (1-1/4 cm) is formed. Allow to dry. Use radiator, or direct sunlight. This should be dried as soon as possible, preferably in one hour.

The patent was filed in the 1930s during a time when power tools were beginning to be being used on production lines for speed and efficiency. The socket the driver interfaces with was given a geometry to ensure the driver cams out of the head to mitigate over torqueing.
Another big inadvertent reason for the crosshaired head's widespread adoption is that it allows the user to use the incorrect tool for the job. The geometry of the fastener allows a wide margin of error in tolerance for whatever size driver you decide to impotently shove into it.
'Course, this only leads to more screws being stripped out, and therefore more frustration in the long run, as you now spend far more time working a bit and a set of EZ-outs, than had you just put your โฅโฅโฅโฅโฅโฅโฅ tools back where they belong and grabbed the right one to begin with.
The truly superior screw head was invented in 1967 by the aerospace company Textron out of Rhode Island, called the Torx head. In a perfect world, anything worth holding down in place with a screw would be driven by this.
The important takeaway of this long-winded sperg post about fasteners is that the inclination toward abandoning and repudiating the American craftsman has been snowballing for a very long time. When it comes to the Phillips head, the medium truly is the message.
Next time you have to deal with one of these abominations, just remember that the reason you're having to do this is because our societal presumptions are:
1. Craftsmanship is dead.
2. You're a โฅโฅโฅโฅโฅโฅโฅ idiot needing training wheels.
3. You're a poor who only owns a #3 Phillips
Many have brought up the important point about the material quality of fasteners, and Chinese metallurgy in general, which must be addressed as an important compounding issue. This is true, and further evidence of American craftsmanship being sold out from underneath you.
