I have started using the titanium replacement blades because they seem to last longer than the regular blades. They are a tad higher in price initially but since I don't buy them as often, I save money. Shipping is great and the prices more than reasonable.
I have replaced blades before but I'm hoping this titanium blade will last a lot longer. I have other trimmers but my Fiskars is my favorite. Small price to pay for sharp cuts!
I will see how they perform, but am very happy with these items. I was surprised to see this type of blades and hope they will withstand the usage for me.
I've been using these replacement blades for over a year now. When I started using them in 2012, they worked well and took weeks to dull. Now, they dull within a couple of days' worth of use. I don't think I've changed the number of times I've been using them in that timeframe. These "titanium" blades don't seem to last longer than the "regular" blades, either.
