Hi
I am looking for a place to buy hand scraper for steel in UK. Since I will only be using this for a single job (For a DIY CNC build), I prefer to spend less and sacrifice some durability. Alternatively a source for carbide scraper blades is also ok as I can make the rest.
Also, I've seen that some blades are advertised as grounded. Is this required for scraping a precision surface?

Thanks
