Here are a few pocket pipes I made, each an experiment in making it more convenient to take a pipe on your dinner date and suitable for a lady or a man . The top one was the first I made a couple years ago and the latest one it at lower right.
Covered pipes are really convenient. You can load and go, close to extinguish, then not worry about dumping it out until you get home. Just slip it back in your pocket, maybe for a re-light later.
These are all about 5 inches (12.5CM) long and, while a short pipe cannot smoke as cool as a long-stem, these are not bad. What IS bad is the photography provided by my phone (my digital camera is awaiting parts). The cloth is green (!) and the pipes are brown, not red. This photo resisted my attempts to adjust the colors, so you have to use some imagination.
The pipe at center, left, has a spring-loaded detent (the tiny steel ball visible near the corner) that fits into a dimple in the cover to hold the cover in place when you close it.
The pipe at lower left has a wooden dome on the underside of the cover that you can barely see the edge of here. It snugs down into the bowl to help secure the contents when closed. The pipe at lower right uses a friction-fit concealed pivot pin to keep the cover where you put it. My thinking evolves each time I make one.
If you want a pocket pipe, I suggest you try one with a cover. Then all you need in your pocket is the loaded pipe and a lighter. The smaller bowls still let you load about 75% of a full size pipe load.
Any good pocket pipe should be made stout to help ensure you don't snap the pipe in half when you sit down or if someone sits on your motorcycle jacket.
