High-grade, precision-ground, premium-steel 45 mm rotary blades offer clean cuts
Titanium blade coating that is three times harder than steel helps the blades stay sharper longer and resist wear, scratches and corrosion.
These work great. They cut through several layers of cotton and linen fabric, leather, faux leather and knits quite easily. They cost a bit more but last longer and eliminate frustrations with lesser quality blades.
There are few words to tell you about these blades but here they are: They are Super Sharp! Although they feel lighter in weight than the blades by Olfa, they do the job very well. These came two in a package, but I won't be using the other one for a LONG time. The last blade lasted 12 and a half years! Good product.
I had used cheaper replacement blades previously and found that they tended to skip against the edge of my plastic ruler, and they didn't roll smoothly. No such problems with these titanium blades; they roll very easily and smoothly, and the cut is crisp and sharp. I have no trouble going through 4 thicknesses of quilting cotton, and someone with a stronger arm could probably do even more. Most of the time, 2 thicknesses is what I normally cut, and these blades do a fine job. My rotary cutter is an Olfa ergonomic, so I wasn't sure whether these Fiskars blades would fit, but they do. I will stick to using them from now on. They're a great product!
I have found Titanium blades much sharper than ones listed as just "steel" and since I resharpen my blades till they evaporate, Titanium last longer. I know they cost a wee bit more but you will be happy with them.
