Sorry to hear about the Tru Sharp. I have been looking at that sharpener for quite a while but didn't want to spend that much money. I was afraid it was too good to be true. As for Harbor Freight, I have never tried the blades, but again, I would be leary about something so cheap. I watch JoAnn's ads and when they have the Olfa blades at 50% off that's when I buy, and it that sale coincides with one of their coupons that gives you an addl. percentage off your entire order, which includes sale items, so much the better.
