Safety razors first had an edge protected by a comb patterned on different types of protective guards that had been placed to open-blade straight razors during the preceding decades.
To maintain the sharpness, razors can be stropped using an old strip of denim.
Safety razors are usually made of razor steel. That is a low chromium stainless steel, and it can be made very sharp. However, it corrodes easily. Drying the blades after using them can make them last longer. Salt from human skin also can corrode the blades, but washing and carefully drying them can make them last longer.

Disposable product
A disposable (also called disposable product) is a product designed to be used only once, and then it would be recycled or is thrown away as solid waste. The word often implies cheapness and short-term convenience instead of something that will last for a long time. The term is also sometimes used for products that may last several months (e.g. disposable air filters) to distinguish from similar things that last forever (e.g. washable air filters).
"Disposable" is an "adjective" meaning "something not reuseable but is disposed of after use". Many people now use the word as a noun or substantive (i.e. "a disposable") but it is still an adjective. This is because the "noun" (product, nappy, etc.) is implied.

Disposable and discretionary income
Disposable income is the income someone has after they have paid their taxes. Mathematically, it is total personal income minus personal current taxes. In national accounts definitions, personal income minus personal current taxes equals disposable personal income.
Autonomous consumption
Autonomous consumption (also exogenous consumption) is when people are paying for things when they have no income. In other words, it is the consumption expenditure that happens when income levels are zero. Such consumption is considered autonomous of income only when spending on these consumables does not change much income is changed; generally, it may be needed to pay for things that are needed and pay off debt. If income levels are actually zero, this consumption is called dissaving. This is because it is paid for by borrowing or using up savings. Autonomous consumption is different from induced consumption because it does not consistently change with income, whereas induced consumption does. The two are related, for all households, through the consumption function:

Consumption function
In economics, the consumption function shows a relationship between consumption and disposable income. It is believed that John Maynard Keynes introduced the idea in macroeconomics in 1936. He used it to develop the idea of a government spending multiplier.
Its simplest form is the "linear consumption function". It is used often in simple Keynesian models:
where formula_2 is the autonomous consumption that is independent of disposable income; in other words, consumption when there is no income. The term formula_3 is the induced consumption that is influenced by the economy's income level. It is generally assumed that there is no correlation or dependence between formula_4 and "C".
Induced consumption
Induced consumption is the part of consumption that changes with disposable income. It is when there is a change in disposable income “induces” (persuades or makes someone want to do something) a change in consumption on goods and services. In contrast, spending for autonomous consumption do not change with income. For example, spending on a consumable that is considered a normal good would be considered to be induced.
In the simple linear consumption function,
formula_1
induced consumption is represented by the term formula_2, where formula_3 shows disposable income. formula_4 is called the marginal propensity to consume.
Ferrodraco
Ferrodraco lentoni, "Lenton's Iron Dragon", is a species of pterosaur. The only known fossil of the pterosaur was found in 2017 north east of Winton, Queensland, Australia.
The pterosaur had a wingspan of about four metres, and when on the ground walked on its four limbs. The name, "Ferrodraco lentoni", comes from the Latin word, "ferrum" (iron), for the ironstone in which the fossil was found, and "draco", the Latin word for dragon. The species also is named after Graham Thomas 'Butch' Lenton, who was the mayor of Winton.
Only small parts of 15 different pterosaurs have been found in Australia. "Ferrodraco" is the most complete specimen found. Scientists have been able to identify five vertebrae, eight limb bones, a large part of the jaw and skull, and 40 teeth. They believe that the pterosaur lived about 96 million years ago. That is in the Upper Cretaceous.
The fossil is similar to pterosaurs found in England, except that it has much smaller teeth. This might be because of the type of food it ate, perhaps a diet of fish. Bones of pterosaurs were thin, and hollow, and because of this, very few have survived.
Winton is well known as an area where dinosaur fossils are found, but this was the first pterosaur discovered here.
Marginal propensity to consume
In economics, the marginal propensity to consume (MPC) is a measurement that can put induced consumption into numbers. Induced consumption is the idea that an increase in personal consumer spending (consumption) happens with an increase in disposable income (income after taxes and transfers). The proportion of disposable income which people spend on consumption is called the propensity to consume. MPC is the proportion of more income that a person spends. For example, if a household earns one extra dollar of disposable income, and the marginal propensity to consume is 0.65, then the household will spend 65 cents and save 35 cents of that dollar. Obviously, the household cannot spend "more" than the extra dollar (without borrowing).
John Maynard Keynes says that the marginal propensity to consume is less than one.
The MPC is higher for poorer people than in rich.
Mathematically, the formula_1 function is written as the derivative of the consumption function formula_2 with respect to disposable income formula_3, i.e., the instantaneous slope of the formula_2-formula_3 curve.
or, approximately,
Marginal propensity to consume can be found by dividing change in consumption by a change in income, or formula_10. The MPC can be explained with the simple example:
Here formula_11; formula_12
Therefore, formula_13 or 83%.
For example, suppose you receive a bonus with your paycheck, and it's $500 on top of your normal annual earnings. You now have $500 more in income than you did before. If you decide to spend $400 of this marginal increase in income on something, your marginal propensity to consume will be 0.8 (formula_14).
Consumer spending
Consumer spending, consumption, or consumption expenditure is when people buy goods and services. It is the biggest part of aggregate demand in macroeconomics. There are two parts of consumer spending: induced consumption (which is changed by the level of income) and autonomous consumption (which is not).
In the United States, the Consumer Spending figure published by the Bureau of Economic Analysis includes three big categories of personal spending.
Aggregate demand
In macroeconomics, Aggregate Demand (AD) or Domestic Final Demand (DFD) is the total demand for final goods and services in an economy at a time. This is the demand for the gross domestic product of a country. It shows the amount of goods and services that will be bought at all possible different prices.
