Assuming this is for more than just the occasional blade, Anthony at Priestner Saws in Aldford, just S of Chester.
Does a brilliant job.
Worth travelling to if you're not within his area.
Very sophisticated CNC machinery plus old style kit for the awkward specials. He has done 14 and 16" table saw blades and planer blades for me and has industrial clients sending in batches of blades from all over.
