Hello drew2229au
The leading edge will be the higher side, with a relief angle going
to the backside face of the reel.
When you have a reel ground, the vast majority of sharpeners will
relief grind. You would need to specify a flat grind to get otherwise.
The reversible reel was an attempt to get extra life out of a reel
between grinds. As such it favours a flat grind.
I do not recommend reel reversal on any reel mower used for domestic
purposes. The better approach is seasonal back-lapping.
Hope this helps.
