Neglecting to sharpen your knife causes the microscopic teeth along the blade to fold and flatten. This drastically degrades cutting performance, making your knife a major safety hazard because the dull blade requires heavy force to cut and is highly likely to slip.
Dull knives require more force and can be dangerous when used with slippery ingredients—so if you're serious about cooking, it's important to regularly sharpen your knives.
3-Finger Test
Lightly place the knife edge on your fingers (sideways, not pointing down) and gently pull. A sharp blade will feel very "grabby" and not slip easily over your skin.
Rule #1: It is important to use a knife adapted to what you want to do / food you want to prepare. For example, you shouldn't use a bread knife to slice a roast or use the blade of a paring knife and use it as a screwdriver (don't laugh, we've all done it!) Rule #2: Don't drop your knife on the floor.
The more you sharpen a knife, the sharper it will get

Cutting boards made of glass, granite, ceramic, or your dinner plate may look stylish or convenient, but they are the fastest way to destroy a knife's edge. These surfaces are harder than your knife's steel. So every time your blade contacts them, it suffers microscopic edge deformation, chipping, or even rolling.

The Tomato Test
Cutting a tomato is the ultimate test of a knife's sharpness. Their thin slick skin, rounded surfaces and delicate insides are hard to slice with finesse using anything but the sharpest of edges. A sharp knife will glide through the skin without crushing, bruising, or destroying the insides.

The best way to tell is by asking the manufacturer of the knife. As a general guide, European/American knives manufactured before 2010 have 20 degree edges while Asian style knives have 15 degree edges. However, there are exceptions to this rule of thumb.
Pull-through sharpeners are the most popular way to sharpen knives, and with good reason: They are quicker than whetstones and more precise than sharpening steels. However, they shed the most amount of metal, which weakens the durability of knives.
