The Microtech Siphon II is what happens when the shop that builds the Ultratech decides the pen in your pocket deserves the same tolerances. It is a solid stainless steel writing instrument with a signature lever action, machined in the USA with the same triangle hardware, serialized clip, and finish work as the knives in the Microtech lineup.
At about 3.9 inches closed, 5.9 inches with the lever up, and roughly 2.6 ounces of steel, the Siphon II writes like a precision tool because that is literally what it is.
Pull the side lever up and the writing tip presents; fold it back down and the pen closes into a compact, snag-free profile. It is a mechanism you will absolutely fidget with, which is half the point of a Microtech. Compared with the original Siphon, the Siphon II adds a longer body with rubber O-ring grips for writing traction and a tip-down pocket clip that carries the Microtech logo, production date, and serial number, just like the knives. Grooves milled into the center cartridge holder show the same attention to detail.
The all-stainless build takes finishing beautifully, and the lineup proves it: bead blast, apocalyptic, and black bodies with apocalyptic or bronze apocalyptic hardware, plus OD green, red, and grey. Signature Series runs add deep-engraved claw and dagger logos and skull-engraved editions, and the very top of the range brings true Marfione Custom Siphons in anodized titanium with copper cartridge tubes. It is the rare pen with a collector ladder.
The Siphon II runs the Fisher Space Pen refill, the pressurized cartridge built to write upside down, in the cold, and on damp paper, and replacements are easy to find when it runs dry. If the Siphon's lever is more machine than you want, the Kyroh is the other Microtech take on the writing instrument, and both sit in our broader pens collection alongside the rest of the EDC writing world.
