Ah, well, it works as a learning material of course.

You might want to look at old lawnmower blades for your future projects. They are not wide enough for a head knife the way they are, but if you have access to welding, that could be a non-issue. Those blades are still made of good still for the most part, except for the cheapest throw-away lawnmowers. Contractor-grade mowers have excellent steel in their blades still ;)

I used this for some of my bookbinding blades a while back

Sandviik HSS Power Hacksaw Blade 700x50x2.5mm

I ground the teeth, and the basic shapes then sharpened carefully

I am using an old hacksaw blade, much smaller, that I made in 1987 to fit my clicker handle, when working in a factory, only ever strop it, haven't had to stone it or rouge it for years. It was one of the old guys there that showed me how.

Best
