My daughter's boyfriend gave me an old lawnmower blade the other day, so I got to work to see what I could come up with.
The steel from lawn mower blades is a bit of an unknown, could be good or not for knives. I cut off a small bit of the steel and heat treated it. It came up trumps, which I was pleased about. The blades are forged, I tried to give a nice smooth forge finish to them. Only the cutting edge is ground. After heat treat, I soaked them into some vinegar overnight to remove the forge scale.
The handles are wrapped with thick cotton thread and I used brown shellac to soak and stick the threads together, which worked quite well. They are not the best looking handes, but for what they are, it's fine.
