Is it worth having 250mm TCT circular saw blades resharpened, or is it cheaper to just replace them? The blades in question are Freud, and cost around £35 each.

its up to you sharpening will probably cost up to 50% of blade, buy a cheaper throw away blade and keep yours for rough work
Well I guess if it would cost that much in Canada it would be twice as much over here, but I don't want a cheaper blade, I really like the smooth cross-cut I get from this Freud LP40M.
Probably cost about £15 without looking up how many teeth your blade has, will cut as good if not better once sharpened.
If you are in my part of surrey try Delta Power tools in Warlingham, usually 7day turnaround as they don't do it themselves. Otherwise look for "Saw Doctors" in yel pages.

Thanks, Jason. It has 60 teeth, and it's still cutting well, but I accidentally found a screw yesterday, which set me wondering about sharpening services.
As The tungsten carbide teeth are harder than your average file, even a saw file I don't think the OP will have much luck. You would need a diamond file to touch up the teeth and need to take equal amounts off all 60 teeth on both the face and top bevel - 120surfaces

Even in the days of CV (chrome-vanadium, remember them) circular saw blades most joiners sent them out as they require a specialist grinder to sharpen. However, there is no way you can hand sharped a carbide-tipped circular saw. Period. There are four facet angles per tooth times however many teeth. Get the angles wrong and the blade cuts like sh*t. And last time I looked saw files didn't work on carbide tips......anobium said:

and for your benefit that is a pre-WWII Disston in a Disston saw vice.

You will be telling me next that you send your hand saws away to be sharpened, or even worse you buy those throwaway type from B@Q.
Tsk tsk tsk
The OP was asking about TCT circular saw blades, if you can tell us your method for hand sharpening them that would be great.

Hey! Enough already! My question has already been answered comprehensively by Jasonb, whose opinion I respect(because I've seen those pictures of his work).
Maybe anobium is thinking of high speed steel circular saw blades or something. To change the subject, I asked in another thread if anyone had an opinion about Tornado router bits from Rutlands, but didn't get much response. Surely someone must have tried them!

My apologies lads, I stand corrected, for some reason I missed the tct reference, but honest I do resharpen my high speed blades and they cut perfectly.
Scrit when did you last use that saw, not recently I think, and the teeth, from what I can see look slightly uneven.
Interesting saw vice but not as good as a wooden home made one which keeps all the blade rigid.

That was taken just before I started to top and refile it. Every time I buy and old saw they're the same - badly out. As to rigidity - you just move the blade along a bit when you need to.anobium said:Scrit when did you last use that saw, not recently I think, and the teeth, from what I can see look slightly uneven.

Incidentally how do you set your CV blades? I haven't seen a circular saw anvil setter for thirty odd yaers
