Maybe I ' m just out of touch with today ' s music , but I feel like they just don ' t make them like Freddie anymore . Edit auto correct strikes again . <| sep |> Patina shouldn ' t affect the effectiveness of your cuts much , if any . There are plenty of old timers cutting masterful stuff with old old darkened carbon . You shouldn ' t be making cuts so deep that the knife gripping into the wood is something you have to worry ability , either . My opinion , at least . What I do , though , is keep my blades in a drawer with a bunch of those desiccant bags that come in shoesfoodetc . This is primarily just to prevent rust , though . You can also wipe them down with a tiny tiny tiny bit of mineral oil too . I regularly do that a couple times a year .
