This is the entire process of hardening blades, and most circular saw blades have at least hardened teeth. Without circular saw blades being treated and hardened, you’d be looking at shattered blades and other mechanical failures. The main reason why circular saw blades are so efficient is due to the fact that they are hardened under the right conditions and are later sharpened, coated, and polished.
If you want to grind the teeth off and have a very thin knife that has no hard steel for the edge, and will bend, then use recip saw blades. A bi-metal blade has a piece of resilient, but not hard, steel as the body, and a small amount of hard steel for the teeth. The honest truth is that few objects that are re-cycled will make a knife as good as one made from a known and proper blade steel.
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.
do circular saw blades make good knives Related Question:
Can you make a knife from a circular saw blade?
The biggest advantage of using an old saw is the lack of metallurgy you need to do. 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. However, blanks cut from the saw are sometimes a little too flexible, but you can work around (or with) it.
Are circular saw blades hardened steel?
This is the entire process of hardening blades, and most circular saw blades have at least hardened teeth. High-quality circular blade are made completely hardened and that’s what you should looking for. You might also find bi-metal blades that have a tough body with an outer rim of hardened steel.
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 can I do with an old circular saw blade?
The best thing to do would be to recycle them at a scrapyard near you. Donate them to a school that has wood shops, art departments, or theater programs. Make interesting pieces of jewelry such as earrings out of circular saw blades. You can use a jigsaw to cut and shape them the way you want.
Do files make good knives?
This mix can make a good knife blade. However, some files are only case hardened mild steel, and underneath the hard teeth is soft un-hardenable steel. Quality brand files, like a Nicholson File, will be hard steel all the way through.
Do old hand saws make good knives?
The high-carbon steel is top for making great knives that take and keep a good edge. The high-carbon steel in hand saws that are over 25-30 years old is also of excellent quality and will make an exceptionally strong knife that takes and holds a fine edge for a long time.
Are circular saw blades high carbon steel?
Yes, circular saw blades are made out of High-carbon steel which is the least expensive and most flexible steel, which means it’s less prone to fracture if it binds, but it bends considerably more easily than other steels.
Does 4140 make a good 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.
What kind of steel is used to make circular saw blades?
Food grade stainless steel blades can be made from 420 stainless steel, however, the preferred grade is either 440B or a proprietary grade. HSS saws are generally made from Dim05 HSS.
Are Damascus blades stronger?
A well-made Damascus blade will retain its sharpness for longer than most production quality blades, but if the goal is to use the best performing blade steel, you may find it elsewhere. In saying that, quality is largely determined by how much it costs. True ‘name brand’ Damascus steel is of the highest quality.
What steel stays sharp longest?
White Paper (Shirogami) Steels There are three types or grades of Shirogami steel: Shirogami #1 – The hardest white paper steel. It will stay sharp the longest but can be a tad brittle under aggressive use.
Is Damascus steel strong?
High quality Damascus steel is not the strongest metal you can get. For most projects and uses, though, it’s plenty strong and durable.
Are used saw blades worth anything?
Old saw blades can be worth some money as scrap material but not a ton. If you have an old saw blade and would like to find out how much it is worth, contact your nearest scrap yard, scrap metal dealer, scrap buyer or recycling center for more information.
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.
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.
