At first glance, you might not realize the Siphon II is a writing instrument, but flipping up the large lever reveals a fluted tip and ball point. The lever-action also keeps dimensions compact, while its stainless steel construction provides substantial weight. The nonreversible pocket clip is firmly attached with unusual triangular-head screws, so removing it is all but impossible without special tools. However, the tiny laser-etched build date and serial number on the clip are a nice touch.

Pros:
– Lever-action mechanism is unique and fidget-worthy.
– Raised rubber O-rings improve comfort while writing.
– Made in the USA

Cons:
– Too small for effective striking
– The lever may snap shut on your fingertips if closed quickly.
– Pocket clip placement can be uncomfortable while writing and isn't optimal for left-handed pocket carry.
