Look up tying sutures on ebay, you will get a lot of results. If they say T/C or tungsten carbide in the title you will need diamond bits to cut the groove to hold the pin, a file wont touch it. They are actually designed for the medical field but work just fine for repining locks. I got my diamond bits on amazon. https://www.amazon.com/gp/product/B07PYTTV8S/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
