I have carved 4 different tampers, several "pipe nails", a classic pipe tool (which I have never used) each has a different use.
I have one I made of ebony for "racing" it has a small tamping area and a dottle digger.
The other three are of various diameters for use dependent on the diameter of the bowl I am smoking. I occasionally use my index finger for a light tamping; been doing that for years.
I also have one made of deer antler that I keep in my ashtray for regular use. The dottle digger end is curved very nicely and is perfect for clearing a blocked draft hole or digging the dottle.
Here are some of them:
