A: Stamp tongs look like tweezers without any serrated rough edge on the grasping surfaces. The best tongs are made of stainless steel and are sold with a variety of points: narrow and pointed, spade shape and round. Personal preference determines what type is most comfortable for you. I use all types, depending on the nature of the job: Delicate stamps with brittle paper may require a wide-tip tong; modern cheap stamps are easy to pick up with narrow points that can damage a stamp's paper if the narrow tips are pressed onto the stamp at the wrong angle.
Go to a stamp dealer's shop and ask to see some tongs and ask how to use them. Cheap nickel tongs are fine for beginners and retail for about $3. A proficient philatelist can hinge a stamp into an album without ever touching it with the hands. Remember that stamps are fragile, and human fingers often have dirt and oils that can affect paper when touched.
