If looking for a small fixed with ease of carry, you might want to consider the MicroTech Medallion. At first I thought the handle being too small would be a problem, but with a lanyard attached, it still fits great, and it has a nifty mini Tek-lok that can mount the knife horizontally on your belt. With your shirt untucked, it is invisible. The sheath is great: easy in, easy out. It can even be used as a neck knife, with very thin cross-section. My first and only fixed blade, and it's with me almost every day. Try to find a used one for around $50, or get a good deal on the internet for around $70.
