Only tools I use to get professionally sharpen were my hand saws, tenon saws. Use to use this firm a lot for sharpening services, if it has a edge, they can sharpen it. http://www.sharpening-service.co.uk/howtofindus.html
2Hr drive. Won't make a special trip, but if I'm over that way, I'll try it. Got a pile of circular saw blades here, all from 12teeth to 48. 30 pence a tooth isn't too bad, one place left that does them here, 60p a tooth. Cheaper to buy new blades most of the time.
Fortunately they are close to me, a 20 minute drive. Could post them, get quite a few blades for a fiver, I use linky below for finding cheap courier. https://www.parcel2go.com/
D'oh! Just noticed the 'Online orders' tab, wasn't obvious on my phone. That's sorted then. I'll dig through that pile when I get home.
