Callahwj,
As serrations go, the serrations on the flat ground Calypso Jr. are as good as any. However, with this particular model, I prefer to take advantage of the plain edged version's superb edge geometry and unsurpassed cutting efficiency. If you get the plain edged Calypso Jr. you've got the sharpest pocket scalpel you're likely to find, whereas if it's serrated, it's just another serrated knife.
Putting serrations on a Calypso Jr. Lightweight is like Hitler's idea of putting bombs on the Messerschmitt 262.
