Unformed officers picked up the order and brought it back to the police station. Alhambra police began investigating the incident as a possible case of food tampering, but soon determined there did not appear to be any malicious intent involved, officials said. The food chopper is used to cut various foods and is done so with a slamming motion. Japanese sword makers developed the technique of differential hardening by covering their sword blades in different thicknesses of clay before quenching.
Thinner clay allowed the heated metal to cool faster, particularly along the edge. Faster cooling resulted in a finer crystal structure, resulting in a blade with a hard edge but a more flexible body. European sword makers produced similar results using differential tempering.
Blades dull with use and abuse. This is particularly true of acute blades and those made of soft materials. Dulling usually occurs due to contact between the blade and a hard substance such as a ceramic, stone, bone, glass or metal. The more acute the blade, the more easily it will dull. As the blade near the edge is thinner, there is little material to remove before the edge is worn away to a thicker section. Thin edges can also roll over when force is applied it them, forming a section like the bottom part of a letter "J".
For this reason, straight edge razors are frequently stropped to straighten the edge. Drawing a blade across any material tends to abrade both the blade, usually making it duller, and the cut material. Though softer than glass or many types of stone used in the kitchen, steel edges can still scratch these surfaces.
The resulting scratch is full of very fine particles of ground glass or stone which will very quickly abrade the blade's edge and so dull it. In times when swords were regularly used in warfare, they required frequent sharpening because of dulling from contact with rigid armor, mail, metal rimmed shields, or other swords,  for example.
Particularly, hitting the edge of another sword by accident or in emergency could chip away metal and even cause cracks through the blade. Folding pocket knives often have a groove cut in the side of the blade near the spine. This is called a nail pull, and allows the fingernail to be inserted to swing the blade out of the holder. S1 A normal blade has a curving edge, and straight back. A dull back lets the wielder use fingers to concentrate force; it also makes the knife heavy and strong for its size.
The curve concentrates force on a smaller area, making cutting easier. This knife can chop as well as pick and slice. This is also the best single-edged blade shape for thrusting, as the edge cuts a swath that the entire width of the knife can pass through without the spine having to push aside any material on its path, as a sheepsfoot or drop-point knife would.
S2 A trailing-point knife has a back edge that curves upward to end above the spine. This lets a lightweight knife have a larger curve on its edge and indeed the whole of the knife may be curved. Such a knife is optimized for slicing or slashing.
Trailing point blades provide a larger cutting area, or belly, and are common on skinning knives. S3 A drop point blade has a convex curve of the back towards the point. It handles much like the clip-point , though with a stronger point typically less suitable for piercing. Swiss army pocket knives often have drop-points on their larger blades. S4 A clip-point blade is like a normal blade with the back "clipped".
The officer was taken to a hospital, where he was treated and released. A DNA sample was recovered from the blade and is being tested, according to police. Officials say there have been no known past issues at the deli.
