Hi , i just got it in today and it is perfect in every way just wanted to share my feelings on this knife i think i will be very pleased. How easy is it to sharpen the serrations with the sharpmaker and how long does h-1 generally hold an edge, i got it in spyder edge because i read that the h-1 gets harder as time goes by is this true, also what or the advantages and disadvantages of the SE over the PE h-1 blade. thanks
