Hi Nick and Norm

I don't have a Deutscher HE660 here to measure blade length and bolt size but there are a few different lengths of Honda stepped blades available so I would look at Honda blades first.

There are probably some stepped blades here I can list the sizes but it would be easier
if I knew what length to look for.

If you want tougher blades then look at a slasher blade.

Cheers
Max.
