You are correct Mr. Wadebevan, it is not easy to sharpen blades made of VG10 steel. Some two years ago I have sharpen Japanese santoku knife made of VG10 steel on Tormek.
After sharpening I have inspected the edge with microscope with mag 500X and have found a wide canyon (left in the picture) and an isolated nick. The nick shows the brittle character of the VG10 steel.
The burr has been raised but I have probably not removed enough steel along the whole blade because the sharpening on Tormek was so slowly.
