You might try Clark's Hardware in Ellicott City (in business since 1845).

Here is a link that might be useful: http://www.clarkshardware.com/

Good idea! My Dad lives in Columbia and I think that's where he gets his tools sharpened - he doesn't own a reel mower, though.

There is a very good place
at Harford road and taylor ave
on the left side going towards
Parkville opposite the shopping
center.

I'd call Gambrill's Equipment if the other places mentioned aren't helpful. He might not do it himself, but I bet he would know someone who can.
