According to their various purpose of using our circular knives are heat-treated to hardness 56 – 64 HRC. in standard modification our circular knives are manufactured without surface treatment; some of our rotary knives can be treated with PVD coatings or with teflon. Circular knives without teeth but circular knives with grooves, or circular knives with ripples on the cutting edge can be manufactured too. In the product range of GSP – High Tech Saws, s.r.o. are also high-efficient cutting industrial knives manufactured on request which are generally known as circular knives.
The blade is already the right hardness for holding an edge, so you don’t need to treat the steel to make it a good knife. If you don’t have an anvil, put your saw blade in a vise and tap the blade as close to the cut line as you can. Now slide your scales back on the knife blade and tap into place.
Using M-2 High Speed knife steel is vital to keeping the edge sharp as long as possible. Hose cut-off blades are available with a smooth edge and a wavy scalloped edge. “SC” at the end of the part number indicates a Wavy Scalloped Edge.
circular saw blade knife Related Question:
Can you use a circular saw blade to make a knife?

Does a circular saw need a riving knife?
Riving knives are also fitted to some hand-held electrical circular and powered miter or cross-cut saws (known generically as “chop saws”). As of 2009, Underwriters Laboratories (UL) requires that all new table saw designs include a riving knife.
Does rebar make good knives?
Steel is not only suitable material for making knives but also an excellent material for forging in general. The metal used in making the rebar is steel, and the knife comes from the rebar. Indirectly, the knife is made from steel, making it a good knife.
What is the strongest metal to make a knife out of?
Carbon steel grades with high amounts of carbon are desirable for knife making because they will give the blade the hardness and strength needed to hold up against impact and wear. However, proper heat treating must be performed on high carbon steels.
What grade steel is a circular saw blade?
Spring steel is commonly referred to as the steel springs are made out of which can consist of different types of steel such as medium carbon steel, low-alloy manganese, or high carbon steel. Circular saw blades are made from high carbon steel so technically yes circular saw blades are made from spring steel.
Are files good for knife making?
You can make a knife from things found in your garage, like old lawnmower blades, car springs, saw blades, and FILES. Of these , a file is probably the only one that will make a decent knife.

4140, also referred to as F5 is a chromemoly steel primarily used for flanges and pipe fittings around industry. It is also good for making dies and whatnot for hydraulic presses and maybe even hammers.
How do you sharpen carbide circular saw blades?
If the circular saw blade is steel-toothed, you can sharpen the blade with a file. A hand file or a crank sharpener may also be used. For carbide-tipped circular saw blades, filing should not be used as files can dull the blade further.
Can you sharpen a 10 inch miter saw blade?
The blade cannot be sharpened while it is still attached to the saw, so you will want to remove it before you begin. Once you have removed the blade, place it on the workbench, over the clamps. Before you can begin sharpening, you will want to mark on of the teeth on the blade using your crayon.
Should riving knife be thicker than blade?
Hi Jeremy, riving knives should be thicker than the saw plate, thinner than the tooth width. If your riving knife meets the above, you’re OK, if not you need a different knife.
Can you get kickback with a riving knife?
When you push a workpiece through the saw blade, the riving knife is designed to keep the two cut sections of the board from closing up, thus pinching the saw blade and causing dangerous kickback. Rip cuts are especially prone to kickbacks, and it is here that the riving knife is most important.
What is the space between two protruding teeth on a saw blade called?
Gullet (handsaw) The space between a saw’s teeth, where the saw dust is carried out. It is an equilateral triangle, just like the file that shapes the teeth.
Is zinc good for making knives?
Galvanized steel is just mild steel with a coating of zinc. Because zinc dust/fumes are generally agreed to be really bad for you and there’s nothing else good about the material for knife making, I’d recommend avoiding it altogether.
Can you blacksmith with rebar?
Rebar is a common material used in blacksmithing. It is affordable, easy to find, and good for practice. It is also low quality, unpredictable, and potentially dangerous to work with. Most projects require higher quality metal, but feel free to make novelty items and practice pieces with safe rebar.
