These blade savers are hard to find in retail stores. I'm glad Amazon carries them. I've had one for two years for the Sanuko blade and it has cracked. I'm not sure why it has, but the smaller savers do hold up. I prefer these to the snap on, just slide the blade in and you are saving yourself a lot of headaches with cuts.
