I have a total of four Alox Vics that I have purchased over the last few years. My most recent perchase was an Alox Solo. Great single blade design but I'm finding that it is VERY rough opening. I have washed in under hot water and applied oil but it has not improved. I thought about sending back for repair but it was so inexpensive I'm not sure it is even worth while. If I can't get the opening to smooth out it will likely be just used in the garage as a throw-away. Any suggestions on now to improve the smoothness?
