Chuckle, Chuckle. Have you used any other MF tool besides the HF?
Other blades?

Think metallurgists who actually know what they're doing, and a
company that isn't trying to cut every conceivable corner in costs.

Yes indeedy. The lesson is I'm not going to take the time dicking
around with a slower cutting blade and having to change it every three
minutes.
The $25 blade is not dead, it's been sacrificed - think of it as
maimed. I still use it where I might run into nails and for cutting
into drywall and stuff. I'm just as concerned with making my dollar
go as far as possible as you are. I just don't think my time has no
value.

Me, too. Thanks. I actually took pictures of the cut off valve and
emailed them to my brother. I knew he'd get a kick out of the
surgery.

So would anything that vibrates at 20,000 RPM.
It's not a question of if the blade will cut, but if it will cut
efficiently and not create problems for me. I happen to think that
wasted blade changes, slower cutting and limited longevity are
problems. I don't think spending money for something of better
quality is necessarily a problem. I have many ways to save and make
money. I don't usually worry about squeezing blood out of my tool
dollars - there are better places to do the squeezing.
