Soaking a knife in the sink can cause all sorts of damage. It can cause high-carbon steels to rust. Wooden handles can swell and crack. If the knife is in the sink with other utensils, they can blunt or chip the edge.
Laying knives in a wet sink throws caution to the wind on many levels. First of all, allowing a knife to sit in water can cause corrosion, spotting, and rusting of the blade. This rule applies to sinks with or without standing water in it. Even an empty sink that is just wet is off limits for a knife.
someone may not notice a shaving sharp knife in the sink and can cut themselves while washing dishes; prolonged contact with water damages the steel, causing the knife to lose its appearance and become dull; water will have a negative effect on the handle if it is made of wood.
And, ``if you leave it long enough, although the knives are stain-resistant, they can get spots on them or rust if you leave them in there all day.'' Even if your sink is full of water, it's not ideal to leave knives (especially carbon steel knives) sitting with any moisture on them.
Secure this with strong tape to ensure that the blade stays well wrapped. For further safety, place the wrapped blade into a padded envelope, bubble wrap or plastic box – tape it all again, before labelling it “Caution Sharp Blade”. It can then be placed into the non-recyclable waste bin, along with your other rubbish.
Do not leave the knife near the edge of counters or tables or in a sink full of soapy water. Use knives only for cutting food. Carry knives with the blade pointed downward. Keep knives sharp.
Consider cleanliness. Wooden knife blocks (just like wooden cutting boards) can become breeding grounds for yeast and mold if you don't dry or clean your knives properly. The cleanest way to store your knives is in a drawer block or a magnetic strip.
Since not all utensils and cookware items are dishwasher safe, and many large pots won't fit in dishwashers, three compartment sinks remain essential to foodservice establishments. Important: Never use your three compartment sink for anything other than cleaning, rinsing, and sanitizing dishes.
The reason you should never put a knife in a sink full of soapy water is because it cannot be seen, and someone could reach in and cut themselves. This is especially dangerous if the knife has a sharp blade. Even if the knife is not visible, someone might accidentally touch it and get injured.
You Store Your Knives in a Drawer
The more knives rub against other tools, the more their blades will dull. This means just opening and closing a drawer can do damage over time.
Never cut on glass, ceramic or countertops. Those surfaces are harder than a knife's edge and will quickly dull the blade. It's what you cut on that dulls knives, not what you're cutting.
Here's why it's also bad for your knives: Leaving your knife dirty, means that a part of the beautiful meal you just finished prepping is still sitting on that blade. Anything acidic or salty or moist is actively trying to eat away at your blade steel and handle.
Moisture is your knife's natural enemy
Setting physical damage and contamination aside, leaving your knives in the sink exposes them to a hidden enemy: moisture. Even if your knives are crafted from stainless steel, prolonged submersion in water can lead to discoloration.
Knife blocks can collect germs if the knives are improperly cleaned or if the block is not regularly cleaned. Knife blocks dull knives over time with the repetitive scraping every time a knife is removed or put back into a knife block. Knife blocks take up valuable kitchen counter space.
Use a sharp knife
A dull blade is actually more dangerous to use than one that is sharp. Here's why: A dull blade needs more pressure to cut, increasing the chance that the knife will slip with great force behind it. A sharp knife "bites" the surface more readily.
A kitchen knife should be sharpened every 1-2 months. Hone every week if you prefer a razor-sharp edge. For your professional chef's knife, you should have your knives professionally sharpened every 1-2 years. However, you might also still choose to sharpen them yourself every 2-3 months.

Concealed carry of a knife is generally legal unless it's a dangerous weapon like a switchblade, and intent to use it unlawfully can make possession illegal.

How to Safely Dispose of Kitchen Knives. Tape newspaper around the blade, and then tape a piece of cardboard around it as well.
