Straight back

Straight back is a style of knife blade that has a dull straight spine along its entire length and an edge that curves up to meet the spine at the tip.

Properties

The long dull spine adds weight and sturdiness to the blade, so knives of this type are heavier and stronger, performing better at chopping and batoning tasks. The back of the knife being unsharpened allows users to apply even more force by using fingers or hand to add pressure and increase the cutting force.^[1] When the curvature begins closer to the tip, the force applied concentrates on a smaller area of the edge, making cutting easier.

While the tip is strong and can have a lot of force behind it, the actual performance will depend on the geometry of the blade: where the edge begins to curve upward closer to the tip, the tip will be stronger but not very pointy. On the contrary, where the edge begins to curve up closer to the hilt, the tip will be more pointed but slightly weaker to perform such tasks as pricking through a tough material.

Uses

The versatile blade shape is good for outdoor and other rough uses. The tip of this blade is very strong, especially in thicker, fixed-blade knives. The curved belly of larger straight-back knives makes them great choppers.^[2] On the whole, these blades are equally good in chopping, pricking and slicing. The simplicity of manufacture makes straight back knives the classic, most common type. The straight back blade is a common design for hunting knives. The curvature of the blade increases the length of the cutting edge, making it easier for hunters to skin animals and cut meat.^[3]
