Stephen, Your question got me interested. The Miller Falls drill weights 1 lb 5 oz and is 12 1/2 in. long. The North Brothers drill weights 2 lb 14 oz and is 15" long. Does that help you.
Stephen, The Millers Falls drill is certainly usable by children. The North Brothers drill is a good bit longer and heavier, not so sure of children using it. Of course it depends on how big they are.
I’m interested in both eggbeater drills to use with my grandchildren. Will these work adequately for them?
