I'd probably go with a short grass blade. When I first got a scythe (from Scythe Supply) for our own little suburban space, I ordered the longest grass blade they had. It's good for wide open spaces, but I find it tricky in narrow areas. That has more to do with my skill level than the blade, of course, but a shorter one would be easier to maneuver. I did pick up a "gardener's blade" from SS later on, which you might want to look into. It's a good deal shorter, and I find that one handy not only in the garden but also for tight spaces in the lawn, etc.
