As Knight Porter’s answer says, light weapons are always eligible for Weapon Finesse, which in Pathfinder means
cestus—Roman, a heavy leather gauntlet used similarly to boxing gloves, but metal plates or spikes could be added to make it much more dangerous
kunai—Japanese, a heavy knife that was really more of a peasant’s tool than a weapon per se. However, ninja famously used them as an all-purpose tool and weapon, since they were easy to conceal and/or explain, and useful for things other than fighting besides.
In D&D 3.5e, there does not appear to be any such weapon. In fact, there are only four weapons with bludgeoning-and-piercing damage that I can find in the entire system—barbed chain, executioner’s mace, maquahuitl, morningstar, and tigerskull club. The barbed chain, morningstar, and tigerskull club are one-handed, the executioner’s mace and the maquahuitl are two-handed.
However, in both systems, a bite attack is bludgeoning, piercing, and slashing, all at once, which is fantastic for overcoming damage reduction, and as a natural weapon is eligible for Weapon Finesse. Natural weapons do have some awkward problems, but it’s still worth mentioning.
Tangentially, you noted feycraft, but please also note Pathfinder’s effortless lace. This is more expensive (though still quite cheap), but arguably easier to come by and it can be added to weapons after they are made, unlike feycraft weapons which must be made that way.
