I have this Benchmade 583-1 that came with an uneven bevel on the left side; specifically closest to the handle. I can get the rest of the blade to the sharpness I desire, which my amateur skills can accomplish, but the area closest to the handle never gets paper-cutting sharp. I only have a flat stone, don't even know brand and it is only one sided, but is there a way I can get the bevel to normal? Or should I just send it it to Benchmade/other service to get it fixed?
