Olfa Endurance Rotary Blade

Olfa Endurance Rotary Blade 60mm, long lasting rotary cutting blade.  We've been testing this blade for over a month now, Gloria has been cutting kits, and I've even grabbed it to cut out 36 crazy blocks, without telling her of course, and she commented today that this blade was still like brand new.  We are sold!  Finally, a blade that holds up!  But, of course, you still can't be running over any pins!
