Much cheaper to buy multi packs of blades vs. a new cutter. Even tho' I have all sizes of olfa rotary cutters the most common I use is the 45. I only buy blades when I have a 60% off coupon from JoAnn's.

Martelli Notions has an on-line sale about 6 times a year where selected items are 50% off regular price. Their rotary cutter blades are THE BEST, bar non.....They last 4 to 5 times as long as any other I have used...The last sale just ended at midnite yesterday.............Check out their website (google Martelli Notions) and yes, their products are pricier, but they are worth every penny!

I have found that I can buy new blades at "Harbor Freight" for very little money. They sell them as "vinyl cutter blades".
