There are many gents folders around, but the William Henrys seem to give a slightly better quality for the money. I, too have been looking in to this style of knives and have found some that may fit the bill in the AG Russell catalog. But most of them are two-handed openers with a lockback. The rest tend to be custom made pieces costing about twice as much.
If you are looking in to Spydies, I would recommend the Viele in VG-10. The look is very classy, even though the G-10 slabs are your standard black. I just wish someone would take that design and use better looking material for the slabs. The blade steel is a premium quality with good heat treat. I have been using mine for about a month now and have still no complains. Most sheeple think it's cute.
One other knife I have had good experience with is the Boker Top Lock II. Under 3" long, with a variety of inserts which give it the classy look. The steel may not be the best available (420 I think), but you can buy a replacement blade in ATS-34. They are of acceptable fit and finish for under $100. They also have one already in ATS-34 and designed by Michael Walker, and very classy as well, but I have no experience with this.
