No matter what type of knife you are looking to buy, one important thing to take into consideration is that profile of the blade. Different blade profiles have have different uses, so I feel it’s important to learn a little about each one, so you can make the correct choice.

Blunt-Tip Blade Profile
I know what you’re thinking. Why would anybody ever want a knife with a blunt tip? Yes, these are specialty knives with very specific purposes. What makes these knives so appealing is the fact that they are much safer. This is perfect for situations such as being on a boat, where the waters can sometimes be turbulent, or in situations where you know medical care won’t be available. Sometimes it’s better not to risk using a sharp blade. An example of a blunt-tip blade would be the sheepsfoot blade.
Drop-Point Blade Profile
Drop-point blades have proven to be quite popular throughout the world. This style of blade has been incorporated into not only chef knives, but also the famous Swiss Army Knife.
A drop-point blade is one which has a convex curve to the spine, which curves into the tip of the knife. This blade style is ideal for everyday use in the kitchen.
Clip-Point Blade Profile
A clip-point blade profile has a mostly straight pine which is just slightly curved, however they clip the spine about halfway down the blade and curve one side to form the tip of the blade. An example of a clip-point blade profile would be the American Bowie Knife.
Spear-Point Blade Profile
A spear-point blade profile is a symmetrical blade which has a tip that is inline with the center of the blade’s axis. This knife is a traditional dagger design and is ideal for use in piercing weapons.
Tanto Blade Profile (chisel-point)
Tanto-style blade profiles are also known as chisel-point blades. The tanto blade style has it’s origins in Japanese blade-making traditions. The tango blade has a single single edge and a mostly straight spine, with a heavily angled tip. Tanto blade styles are extremely popular in the folding knife market. The only issue with these knives is that they can be harder to sharpen.
Traditional Blade Profile (simple)
Simple blade profiles are the most common form of blade. These combine straight spines with curving edges which meet in the middle to form the tip of the knife. This is a very strong and sturdy blade which is great for survival purposes.
Trailing-Point Blade Profile
A trailing-point blade profile has an edge and spine which curve upwards to form the tip of the blade. An example of this blade profile would be a fillet knife. These blade profiles have also historically been used for slashing weapons.
There are many other types of blade profiles out there, but I think this is a good basis to give you a general understanding of the various blades available on the market.
