As nice as the fitment mechanism is in the screw-cap pen, I can't deny the convenience of a clicky pen.
Well, months have passed and I never ordered the clicky from Big Idea Design. I did play with some very nicely machined Chinese solid brass pens sold on Amazon under brand names like "Copplus" and "Ekloen", but in the end decided that so many of the machined pens were simply too long to fit in my front shirt pocket.
There has been an exception to that for the last few years, the EDK pen from Karas Kustoms. At barely more than 5 inches and using the popular Parker/Schmidt ballpoint refills it seemed ideal except for that pesky warning on the web site. It stated that the clicky mechanism could wear out if abused and I'm thinking "on a $70 pen? Seriously?"
Recently Karas has introduced "V2" of their click pens (the Retrakt and EDK). Both feature a redesigned and more durable click mechanism fabricated from stainless steel. The redesign also addresses another (unknown to me) complaint about the original design: the tendency of the two halves of the pen to unscrew in one's pocket. This was fixed by greatly lengthening the threads between the top and bottom halves of the barrel and by adding a "collar" below the threads on the nosepiece which houses an O-ring for added friction.
As the intrigue of brass had caught me in the last few months, I went for the solid brass EDK V2. It is solid and
heavy, fits nicely in my pocket, and has a raw finish that I will never care about getting abraded away like anodized aluminum. The feel on the clicky isn't the
greatest but it is perfectly functional. I might just go for the Retrakt (which is engineered for the Pilot G-2 refill) but that's for another message in the future.
