I'm looking at buying a replaceable blade Ryoba and while looking
around I have been wondering about something:
The cheapest ryobas have tip-hardened teeth while the more expensive
saws have fully hardened blades.
I can't for the life of me figure out the purpose of a replaceable
blade, that can be resharpened.
As far as I understand it, it is almost impossible to sharpen the
blades yourself and anyway that would defeat the purpose of the
replaceable blade. Having the blade sharpened professionally will be
more expensive that buying a new blade and can only be justified with
expensive handmade saws.
The blade will dull faster than a tip-hardened blade (right?), so you
will end up buying more expensive replacement blades more often.
What am I missing???
