Blade Sharpening
Here is a dumb question, but one that has me wondering at night:
I hear a lot about sharpening saw blades and there are recommendations on the Forum but-
Surely you can't sharpen a carbide-tipped blade once the carbide tips have worn down so that there is no more kerf on the blade? It needs new tips, doesn't it? And the cost of doing that must be round about the cost of a new blade (especially on special)?
I've kept my old blades just in case, but I'm sure they are worthless now.
Cheers,
Carry Pine

Yup once they wear down so much they cannot be sharpened without retaining the same kerf dimension and tooth profile, time for a new blade. hang the old ones up in the shed for decoration.
I suppose if you were really attached to the blade body and wanted it re-tipped, you probably could, but a new blade would most likely be much cheaperHow much wood could the woodchuck chuck if the woodchuck could chuck wood?

Hang them up?!
The steel can be used for marking knives and scrapers.

You dont loose any kerf, they remove metal from the hight of the tooth to sharpen.

Thanks guys,
restful nights- but lots to think about.
Harry72You dont loose any kerf, they remove metal from the hight of the tooth to sharpen.
Harry, the carbide tip has worn on the side so the tip is only as wide as the main part of the blade.
The other guys were on the money but of course Derek gives me more to think about. Yes, it is good steel. I won't dice them any more.
Thank you for your replies.

Hi Ian
Think of blades for the #80 and #112 ... actually a stiff cabinet scraper is excellent as well - just give it a touch of camber.

Hi Derek
your hands must be a lot stronger than mine !!
(very tongue in cheek) and I thought you prefered the Stanley and Veritas scraper planes (with their 1 to 1.4 mm blades) over the L-N version with it's 3.5mm blade
but I agree with you the steel is tool "nice" to waste as a wall ornament
spend as much of the weekend as you can in the shed (or on the veranderah)

I just had 6 blades sharpened, both rip, cross cut and triple chip. They are all done the same way.

I just buy a new blade but then again I don't buy really expensive ones

Do you guys have any suggestions for someone in Sydney to sharpen saw blades that'll do a good job? Or are they all much the same as each other?
