Hey folks! I've heard two lines of thought on sharpening hooks: 1) Today's premium hooks such as Gamakatsu, Mustad, etc. are "chemically sharpened" (whatever that means!?) and should NOT be touched with a stone or file or 2) Every hook (especially after a hang up, snag, or fish) should be sharpened. What do you all think? Also, what is a good sharpening tool or stone? Thanks, Wood Man
