I am in Florida, where as little as a summer week in a hot vehicle can destroy a fine pen. Not a Fisher though. My work-pen has seen two years now and still writes. And a Fisher draws a substantially longer line than just about any other pen. Obviously the GraphGear is indifferent, but the nib is its achille's heel, and it can bend without serious abuse. For that, I use a Write in the Rain 1.3mm, which is also dear to me and doesn't flinch on a sodden 2x4 one bit.

PS: I highly recommend the Fisher raw brass version. It ages with character, is partly anti microbial and is an all around great pen. This is the part where self defense becomes an issue. But I swear I am not sponsored. It's honest fanatacism.
