Yes they have been heat treated. However, some people will anneal them to make them softer so they can work them easier. Once they've profiled the file out, they then will have to "reharden" it, which means they'll need to HT it again.
Re: Tempering a file knife
Tempering releases the stress in steel from quenching. After quenching, the steel is so brittle it can be broken by hand, tempering gives it its toughness back.Railroad spikes are readily available, usually for free, they are a novel item, and they can make a perfectly useable knife. However, they simply do not contain enough carbon to make a good blade. One big misunderstanding comes from railroad spikes that are marked "HC" for "High Carbon".
There are four different grades for American Pattern Files: Coarse Cut, Bastard Cut, Second Cut, and Smooth Cut. They range in that order from fewest to most teeth per inch.
The best metals for making knives are: Tool Steel. Carbon Steel. Stainless Steel.
They make good knife blades. Make sure you anneal (soften with high heat) the blade blank before you start grinding and filing. You will have to harden and temper as normal when your done shaping. I prefer using mower and edger blades because if you make a mistake throw it away.
S30V is the best blade steel available today.
- Superior edge holding.
- Improved ductility.
- Good hardness- ideal range Rc 59.5-61.
- Good corrosion resistance.
- Very high amounts of Carbon and Vanadium.

Those for cutting wood are called wood-, cabinet- or pattern-maker's files. Mill files may be used to shape wood (they perform best on hardwood); however, wood files will not withstand use on metal. These are used to shape and smooth flat surfaces. Files with one semicircular surface and one flat are called half round.
the most common types of files you'll see are flat files half-round files round files which are round. but also tapered towards the end hand files which are square and straight in every dimension triangular files which are triangular in cross-section.
For filing soft metals such as aluminum and brass, and also for filing plastic, files are made with semicircular rows of teeth, resembling sections of overlapping disks. These are called curved-tooth files. Special files called rasps, for use on wood only, feature individually raised, extremely rough teeth.
DIY Frequently Asked Questions / What's the difference between a file and a rasp? A file is generally used to smooth metal, where a rasp is specifically designed for shaping wood.
A rasp is coarse form of file used for coarsely shaping wood or other material. Typically a hand tool, it consists of a generally tapered rectangular, round, or half-round sectioned bar of case hardened steel with distinct, individually cut teeth.
File, in hardware and metalworking, tool of hardened steel in the form of a bar or rod with many small cutting edges raised on its longitudinal surfaces; it is used for smoothing or forming objects, especially of metal.
Warding files are machinist's files and are frequently used by locksmiths. They are named after the shaped openings in keyholes that act as a barrier to lock picking, as they are used to both deburr and repair them. They can also be used to file the notches in a key that allow it to fit into the warding.
The basic principle of file-making is to cut teeth into a metal strip to provide a rough tool that can wear away material from a softer surface. While files were produced by hand for hundreds of years, they can now also be mass produced by machine.
Definition of rough file. : a file of the grade having the coarsest cutting ridges.
A file is a collection of related information that is resident in the file store and is identified by a unique filename. The UNIX operating system understands three different types of files: ASCII Files: This is the most common type of file found on most systems.

Name comes from where the practice was implemented first. Organizing folders by 100s became the gold standard for a while and thus were named California folders. It's the state that started to use them first.

It was found in Crete in the Mediterranean. The Egyptians used brass and copper rasps from around 1200 BC. Iron rasps were used by the Assyrians in the 7th Century BC.
File folders can be made from plastic or paper. When paper is used, it is preferable that it is made from paper pulp with long cellulose fibre, such as kraft paper or manila paper.
There are three basic types of special files: FIFO (first-in, first-out), block, and character. FIFO files are also called pipes.
You have two basic methods: straight filing and draw filing. Here's the difference between the two: Straight Filing: The first and most basic filing technique is called straight-filing, and involves pushing the file lengthwise across the work, making contact only on the forward stroke.
There are many different types of files: data files, text files , program files, directory files, and so on. Different types of files store different types of information. For example, program files store programs, whereas text files store text.
Files are classified according to their cross-sectional shapes, the form of the cutting edges, and the coarseness of the cut (i.e., the number of teeth per inch or centimetre). There are three general classifications of tooth form: single-cut, double-cut, and rasp.
File Identification and Profiling
A file signature is a unique sequence of identifying bytes written to a file's header. On a Linux system, a file signature is normally contained within the first few bytes of the file. Different file types have different file signatures. For example, a Portable Network Graphics file (.- MARKING AND MEASURING TOOLS: STEEL RULE:
