The right knife can change your entire kitchen and we've rounded up 20 amazing options on sale

Quality knives matter -- and in more ways than you might expect.

At the most basic level, having a functioning set of proper kitchen knives means you can actually get in a kitchen, start putting together a meal and have the right tools to handle all tasks. From the blunt force of the clever to the skilled precision of the paring knife, you're ready.

But do you know what else a well-stocked knife block in your kitchen says to visitors? It says an adult uses this kitchen. Butter knives and pizza cutters will only get you so far in life, gents. At some point, a lack of quality knives on display in your kitchen might as well scream that your culinary skills haven't advanced beyond reheating fish sticks in your illegal dorm toaster oven.

That's a bad look. To save you from yourself, we've assembled 20 (yes, 20!) deals on worthy knives and knife sets. And since these deals coincide with the Presidents' Day holiday, enter the coupon code PRESIDENT15 at checkout and take another 15% off each of these offers.

All we're saying is...invest in yourself.

Chef's Knives

If you purchase nothing else, at least lock up the services of a quality chef's knife. It's the most important tool in any chef's arsenal and can sub in to handle almost any kitchen task like a champ. Another consideration is going with Damascus steel blades over standard stainless steel. Damascus steel, which is actually an iron and steel alloy, producing brilliantly intricate, eye-catching blade patterns.

Of course, different sizes of chef knives work best for different jobs, so to get the true impact of this tool, consider the various 2-piece ($59.99, 56% off), 3-piece ($44.99, 50% off), or 4-piece ($74.55, 25% off) sets also on sale.

Clever

We've all seen horror movies, so we're all up to speed on the power of the bulky clever for heavy duty chopping and rending. Quality is the name of the game with a Damascus Cleaver Knife with a buffalo horn and mosaic pin handle ($59.99, 59% off) that looks as sharp as it is.

Fillet knives

Thinner, longer and more flexible, fillet knives are made to cut items like thin fish slices. It's a specialty piece, but whether you choose the rosewood ($53.55, 25% off) or buffalo horn ($53.55, 25% off) hilted blades, this is an item that says you're serious about your food prep.

Paring knife
