Thanks for the warning. I will be checking more often. I too like the Olfa cutter that I have where the guard automatically retracts once I let go of the cutter. I don't have to worry about it falling off the table and cutting my foot or picking it up the wrong way. I had one where you had to slide the guard over the blade and more than once forgot to do so. I won't have any other kind than the Olfa ergonomic again.
