thanks for the info and wouldn't you know it I just got rid of old blades a few days ago then come to find out I didn't have any blades to save my soul.... so I went to joanns real quick forgot my coupons(ugh) and they were totally out of blades then went to acmoore and ended up paying $7.99 for one blade so I went to sharp website and I see on the web site that you can order a pk of 10 olfa 45mm for 38.00 that's $3.80 a blade and free shipping so I am ordering some your post was good timing for me thanks
