Question about saw blades

ok im new, this is my first post. i usually use the bladeforums but i dont want to so here it is.

I have a circular saw, it uses carbide tipped blades, it runs expensively and when im done with blades, i dont throw them out be cause i always find a cool use for them, sometimes i make clocks, sometimes i make tables with them etc. But what im really wandering is, can i make a knife out of them? do i have to heat treat them? ( blades for a saw are allready heated)

so whats your opinion?0] 0] 0] 0] 0] 0] 0] 0] 8o

carbide tip blades

I am also a cabinet maker and have found out that blades that are carbide tipped are not good for knife blades. They use a steel that is of lesser carbon and depend on the carbide cutters to do the job. When I make a blade, the one thing I have to know is the type of steel and how to heat treat. My recommendation is to keep making clocks.

There are some saw blades that do make good knife blades. The really old large saw blades, from saw mills, was hand forged blister steel and 1095 improved. Both make excellent blades with a 3+3 HT, normalize twice before HT. The blades that were made right before the carbide started showing up were generally L-6, and that also makes a good blade. If in doubt about the steel, HT a piece and check it with a file for hardness. Be sure your file gets thru the forge scale, or outer carburized surface.

Saw blades

I agree with Ken, I use a lot of old saw blades and the newer ones are generally 15n20. Great steel. The older ones are L-6 as well as older lg. band saw blades. Just anneal and go for it.

A word about bandsaw blades. The big bandsaw blades from saw mills are 15n20, these are the blades that are 6+ inches from teeth to spine and vary in length but probably 20ft or so minimum. These are the 15n20 ones. The smaller bandsaw blades that are about 15ft long and only an inch or two from teeth to spine are not 15n20, they are 1075 or 1084.

I traced this issue down after having someone donate an entire trailer load of 1.25" X 15' saw blades to me. I thought they were 15n20 and made a damascus billit out of them with 1084 as the other steel. There was no pattern (other than welds themselves) showing after etch. I called the manufacturer and worked my way back to the steel mill that made them. I was told that it is an industry standard that only 6+ inch blades are 15n20.

This can save you time if you want to use bandsaw blades for any damascus.
