Not according to the CSR I spoke to on the phone after calling their 800 numberHey there Fastball, sorry if we misled you here but the Spyderco is NOT THE BEST CHOICE for reshaping knife shoulders, that takes a grinder or belt removing lots of metal; were talking edge sharpening for under $100.00 and something the Spydies do very well. I use an old verticle grinder with several different grid 42 x 1 inch belts for shoulder shaping or forming a new piece of steel...

This, cant go wrong.Spyderco is easy to use and makes a great edge.
