I just thought it was a discussion and enjoyed it. I didn't have any luck with the HF blades but don't consider stating that to be a complaint. It's a fact.
I'm curious about the titanium blades too and found some on Amazon for the 45mm cutter. I may try them. I use a 60mm cutter but bought a 45mm so I could use the HF blades. I just started to learn last year so it's all new to me and I love reading the different points of view and the wonderful tips.
