You've opened a can of intrigue
. In general, serrations increase the cutting edge length, because all those little scallops are longer than a straight line. The points also make contact with material first, and tend to protect the inner edges. Those two factors add up to an edge that can generally go longer between sharpenings. Serrated edges are ground only on one side, while plain edges are ground on both sides. So, serrated edges cut a bit differently. You'll also need a sharpening abrasive, like the rods in the Spyderco Sharpmaker, that's basically a rounded point triangle to get into serrations. The technique is just slightly different than sharpening a plain edge, so nothing to worry about. There are threads here on sharpening serrations that I or someone else can find if you want more info.
Now, into the rabbit hole. The H1 steel that most of the Salt knives are made from is some interesting stuff. In plain edge it holds an edge about like 8Cr13MoV, so if you've never never used a steel like VG-10 or S30V you won't notice any lack of performance. In serrated edge, Sal (the founder and owner of Spyderco) has said that H1 has the highest edge retention of any steel Spyderco has ever tested. Serrated H1 has edge retention beyond the normal increase of just having points and a longer effective edge length. There's some evidence that H1 gets work hardened when the serration are cut into it, but Spyderco's engineers still can't fully explain it. It's like there's some Japanese voodoo going on (H1 is made by a Japanese company).
LC200N (the other steel Salt knife blades are made from) has better plain edge retention than H1. Sal and several folks here say that LC200N is between VG-10 and S30V for edge retention on plain edge blades. One fairly well known YouTuber who does rope cutting tests got better performance from plain edge LC200N than he did from plain edge S30V. LC200N still shows improved edge retention in serrated blades, and displays very good toughness. Here's a link to Evil D's serrated LC200N torture test that pushed me over the edge to getting a Native 5 Salt with a serrated blade instead of a plain edge blade - viewtopic.php?f=2&t=85045
. I have nicer and more expensive knives, but that serrated LC200N Native 5 Salt is the knife I carry almost every day because it performs so well.
My only hesitation with the Ladybug is that it's so tiny, and it's really a two finger knife for all but fairly small hands.
