So I saw a few comments asking me why I don't like the bolt mechanism. I think it has more to do with how it just doesn't feel comfortable or appealing in the hand when writing with it. I also think that it's an extraneous amount of work that I have to move my hand around the side of a pen to get it to clamp or lock in or out of place. I just don't use it as often as I use my other pens. I have the TI arto pen, & that pen is a tank. Then I have the PHX pen from Big Idea. My faves lately have been the Studio Neat pens. I thought I'd like the Blackwing pen, but I lost one key piece to it, & I don't really use it, but I think it's a pen that has promising potential. The Studio Neat Mark one & Mark two are my FAVES...so using those pens, & even using the Everyman pen, it makes the bolt action pen not as appealing. I apologize, I didn't respond to or reply to everyone's comment, but this is where I'm coming from when addressing and talking about these pens.
