Just seen my poor spelling. This is the guy I use, https://www.tuffsaws.co.uk/index.php?route=account/login but you probably have some experts over there. If you ask on this site, someone may pop up to lend a hand and point you in the right direction. Remember, it’s not just the blade, it’s the tuning of all of it. Good luck
