There was a railroad that ran through town. About 20 years ago they tore it up. You can still find spikes and assorted hardware along the trail.

Nice! I used to have a cool one that was twisted a lot and the end filed into a blade. Wish I still had that knife.
Looked similar to this
Willing to send you this 3 inch spike, or send it to a blacksmith of your choice. Will make a nice smaller version of your knife.
You just gotta cover postage, no pressure, feel free to say no.
