The first titanium blades I tried were Olfas. I didn't see any difference from their regular ones, honestly, other than being more expensive. If fact, right after I put one in, I ran over something - don't remember what - and ruined one of them. That made me angry with myself.
I've only used Headly titanium blades from Amazon for a few years now. I think they are $16 for 15 blades, so an incredible deal. They do have ones that are not titanium, but given the low price I am paying for these, I have not tried their "regular" ones. After so many years of pricey blades, I still have to remind myself that these are not as expensive and it is OK to change out when I start getting skips.
