Saw an ad on Facebook a few weeks ago for these blades...thought what could it hurt to try them. These are not like the Harbor Freight blades that won't cut hot butter. These blades are the sharpest I've tried. Better than Olfa and Fiskars. I ordered the 10 pack and mine are gold colored, maybe for titanium?

Once again, I'm not in co-hoots with the company, just happy to have found what for me is in exceptional blade.
