I wouldn't worry about it at all . The Vic Alox ( and Wenger Si ) are some of the best built production knives you can get . Problems with them are very rare . Sounds like its just a breaking in proccess to me . If they get gritty to open or close or start to loose their snap then wash them in soapy water and scrub with a tooth brush , open and close the blades and tools several times under water , rinse then dry well . Don't forget to add a little oil to the joints .
