Knife blade grinds are the angles and shapes of the cutting edges on a knife blade, which determine how the blade performs in various tasks. Here are the main types of knife blade grinds:

• Chisel Grind: This grind is characterized by a single, straight bevel that extends from the spine to the edge. It offers excellent strength and is suitable for chopping and easy sharpening. However, its cutting ability can vary depending on the angle and design.
• Convex Grind: Also known as the Moran Grind or Appleseed Grind, this grind features a convex curve towards the edge, with a lot of steel in the middle of the blade for reinforcement. It is popular for its durability and strength, especially in choppers, machetes, and axes. However, it can be difficult to sharpen and may not be the best choice for smaller knife formats.
• Full Flat Grind: This grind extends from the spine to the edge bevel in a flat, linear slope. It is versatile, offering a balance between strength and sharpness. It is suitable for a wide range of tasks, including chopping, slicing, and general-purpose use, making it popular in kitchen knives and hunting knives.
• Sabre Grind: A sabre grind is a flat or hollow grind where the primary bevel does not cover the entire width of the blade, leaving some portion unground. It is known for its excellent durability and is often used in military and tactical knives. However, its cutting ability is typically less impressive than other grind types.
• Compound Bevel: This grind combines two different grinds, such as a Scandi/hollow combination, to leverage the strengths of both. It is popular for its added durability and style, making it a great choice for knives that require both strength and sharpness.
• Hollow Ground: A hollow ground blade features a concave curve from a spot below the spine down to the edge. It is known for its sharpness and durability, making it ideal for slicing and food prep. However, it may not be the best choice for heavy-duty chopping.
• Scandi/Sabre/V-Grind: Often found on outdoor bushcraft knives, this grind is characterized by a rectangular (unground) blade that transitions into a V shape partway down the blade. It is easy to sharpen and offers a strong blade, making it suitable for tasks requiring strength.
• Asymmetrical Grind: This grind features two different grinds on each side of the blade, combining the best of different angles to create a durable edge. It is known for its hard-wearing strength and durability while still being sharp.

Each grind has its own set of strengths and weaknesses, and the choice of grind depends on the intended use of the knife. For example, a full flat grind is versatile and suitable for a wide range of tasks, while a hollow ground is ideal for slicing and food prep. The sabre grind is known for its durability, making it popular in military and tactical knives.
