As the original edge of the knife was rather blunt i gave it a new one, after grinding the old apex flat on the Tormek by using a combination of Rubber Wheels coated with diamond grit to create the new bevels & various Paper Wheels with fine diamond compounds for the finishing steps.Now photographing shiny metal to resemble accurately what it looks like in real life will always remain difficult (especially with a cheap camera like mine), and this edge is no exception: what at first glance may look like a polished edge is in effect just a polished toothy edge, but one that is easily hairwhittling sharp yet has noticeably more bite than expected.The new edge is ever so slightly convex and it's apex fits in the 30 degrees inclusive slot of my Tormek WM200 angle guide.(You can click each pic 2 x for more detail)
