Flattening back of chisel

[Spad011]

Being a new user, I've tried to ensure a flat back on my chisels and plane irons.  I know that using the side of the wheel shoul flatten them.

When I do this I get irregular streaks on the back and can feel that there are deeper areas ground by the wheel.  It looks like a couple of curved streaks.

Obviously doing something wrong..any ideas?  TIA

Approach the wheel very carefully with your tool and keep pressure on the blade firmly, and positioned to force the blade flat on the stone.

Your curved streaks are coming from the corner of the stone because your pressure is not placed correctly.
