Default How to Make 'X-ACTO' Knives

To All:

Often times we have the need to create small but accurate shapes in
metal or wood.

Collect all of the blades in a shallow pan and cover them with an
eighth of an inch of motor oil. Now set the oil on fire. Allow the
fire to burn out. It's going to be smokey as hell so you want to do
this outside of your shop. When the fire goes out, tip the blades out
of the shallow pan onto a piece of iron and allow them to cool.

Once the blades have cooled you may continue with your sharpening.
They should take a razor edge. If they crack, you've either left them
in the bomb too long or you've cooled them too fast. The tempering
(ie, burning-off) should not effect the cracking one way or another.




Robert,
You are simply amazing. Your directions fit right there with what all my
father attempted to teach so many years ago. (The forge is long gone).

But the tempering process . . . is there a method less smoky and noxious?
For the faint of heart who live in an area where the neighbors are less
tolerant of flames and smoke?

Thanks

Certainly, try a table top furnace and KaseNit.
