So I've only just realised (through using some brand new, but very cheap, clippers that were my Dad's that he never used) that my c.10 year old "BaByliss" hair clippers are actually very blunt, despite oiling and cleaning them fairly regularly.
Question is, what to do with the old ones - can they be re-sharpened or just better off to bin them and get some decent ones? They weren't megabucks in the first place from what I recall but would still be preferable to renew rather than bin them if possible.
Any hairclipper experts on here?
