So I have a well used salt 1 that after a mixture of mine and anothers ignorance has shallow serrations. I sent it to spyderco to see if they could fix it and did a good job fixing my mistakes but the edge just isnt what i remember it to be. I asked them to re-profile the serrations but they said that would remove too much stock from the blade. I remember cleanly slicing corners off of paper (my standard sharpness test). I need help bringing the serrations back to scary sharp, its a user edc blade so thats all that matters to me. It kind of tears things right now. I am armed with a spyderco sharpmaker (fine and medium). Can any of you sharpening gurus help me out?
