I have been looking for a robust pocket pen for ages. So far it is either the kaweco supra or the sport in steel. However, I am contemplating if I should grab the pilot e95s for the same price as these. My main condition is that whatever pen I am buying should survive in my jeans/trousers for at least two or 3 decades, as I won't be splurging on a fountain pen any more (For now!). #lifestyle source
