A relief cut on both sides allows the hack saw room to fit in.
Now I need to cut along the lines between the cuts.
Blade material is selected. A Terry Ragon thumb screw is hand
serrated and cut to size.
The finished bar is now ready for some pre-industrial machining.
The blade width is laid out and holes are drilled to remove excess material.
This will all be hand filed later.
The knife blade is roughed out and ready for finishing.
