$1,234 · Old ready to be discarded machine planer knives/ blade wanted

Looking to make a project at home, with a single knife or more if possible. Old, dull, used, beat up, dented, chipped, knive/s would be welcomed. Replaced your old ones with a nice carbide model? I'll be glad to use the old ones if you like. I am hoping that they will be free, instead of going into the landfill or recycling. I'll pick up of course. Tx!
