Yes, they'll fit the 45mm Olfa!! I just checked mine. It has a round peg for the blade to set on so that's all the blade needs is a round hole. I'm going to my Harbor Freight tomorrow to see if they have any of the blades available since they're on backorder on the website. I'll probably go to the next town too to buy some there if they have them,lol!! I'm stocking up if I can!!
