This slim and modern potentiometer is small and compact, yet looks good and has a nice feel. We hand selected the best knobs for your project in different sizes and varieties.  This one is the Slim Metal Knob 10mm diameter x 10mm Tall (T18 Splines). It's a brushed aluminum knob with a shiny black (anodized?) coating.  It kind of looks like the type of knob you'd find in a very fancy, modern kitchen.  There's a silver mark on the black finish so you can know where you are and figure out where you're going.  It's a good knob if you're looking for something basic and subtle and it's super tiny and subdued.  We also have a taller version in the same style. This knob will not work on our Rotary Encoder (which has a D shaft)! It will work, however, on all of our Potentiometers (which have T18 shafts)
