Making a Custom Knife from a concrete saw blade

[Ron Kulas]

This blade is over an 1/8 of an inch thick. I am using a 24 inch diameter concrete saw blade.



I cut a chunk of it away with a angle grinder.



This will be a hunting knife with a drop point and a finger guard.



This is a very thick blade.





Next, I heated the blade cherry red and let it cool very slowly to soften the steel. so I could drill hole and grind a bevel and do some file work.



this time I am going to do a "W" pattern on the backbone of the blade. I marked off the spacing with a sharpie.



Then I used a small square file on one side of the blade.



Then turned the blade around and did the other side.



I added a little bluing to bring out the details.





With all the file work done, I heat treated the blade by heating it until it was non magnetic (around 1500F) and then quenched it in 130F salt water. Next I temper it at 400F for one hour. Finally I polish the blade to a mirror finish.

I used curly maple and aluminum pins. I'm calling it "Blonde"











The last step is to make a sheath. I use 7 Ox. Veg. tanned leather and then dye it to the color I want after I sew it.










I went back to that saw blade to make additional knives.




with alum. bolsters and a Cocbolo handle. I also used homemade mosaic pins.
