Rotary knife troubles

[epiphanist1248]

I have a cheap 45mm rotary knife that doesn't cut because the blade doesn't spin. I tried changing the blade but no difference. So I was thinking of getting a name-brand blade on the assumption of better quality control.

Can anybody tell me: is a 60mm blade really any better than a 45mm blade? And is Olfa substantially better than Fiskars or just more expensive?

I have a Fiskars rotary cutter and it works great!  I bought extra blades on Amazon for much less than they cost at my local Tandy store, but I have not had to change the blade yet, so can't comment on whether they are as good as the factory blade that came with the Fiskars cutter.

I have a 60mm Fiskars I got at Walmart. I love it. Haven't had to change blade yet either. I think 60 is better for thicker leather.

I have the 45 mm from Tandy and hobby lobby. The Tandy one is complete junk. I should have returned it. But I throw away receipts. My wife bought me the one from hobby lobby for Christmas and it is great. I haven't had to change the blade and it is way more sturdy than the Tandy one.

I have had a 45mm Fiskar for about 30 years that has worked really well. Recently purchased a pack of 10 blades off ebay for about $5 and they work just as well as the brand name blades I was buying.
