I saw these at Nancy's Notions.
Has anyone used them? Do they really stay sharper longer?

My hubby says, yes. He says in milling cutters and such the titanium and nitride does improve them, so it should be the same for the rotary blades.
Bye the bye, love your avatar. I recently found a 431G in a pawn shop. It chainstitches.

I believe they will stay sharp longer, but are they more knick proof? :D:D:D

I just saw them on Nancy's Notions and wondered if they are worth 2 blades for $10.
