I have an Olfa 60 which is my go to for cutting strips and yardage and I have an Olfa 45 that I use occasionally - it's basically an upstairs/downstairs situation. I recently got a mini Fiskar cutter that I received from a board member as part of a Secret Santa. I tend to use the mini for cutting curves and around templates. My choice if I had to buy a new one would be an Olfa 45 or 60 - but if you have on already it's much cheaper to just buy a new blade.
