This is the Rite in the Rain No. BK16 bolt-action pen in matte black metal. The pressurized cartridge writes at any angle, underwater to 35 feet, and across a -30F to 250F range, with permanent ink that will not clump or smear through water and grime.
It works gloved and one-handed — run the bolt with a thumb, write, and holster it back on the heavy clip. The balanced metal body sits steady through long note-taking sessions on all-weather paper.
Rite in the Rain has made all-weather writing paper in Tacoma, Washington since 1916, when it was developed for logging crews in the Pacific Northwest.
