Hi all, I recently received my Ti-Scribe bolt pen and pencil from Kelvin at Urban Survival Gear. Both of mine are in copper. The action on both are super smooth.They are both comfortable to write with, the weight and diameter feel nice. My most carried pen is the Hinderer Investigator which is dwarfed by the Ti-Scribe. It is not that the Ti-Scribe is huge, the Investigator is just very compact. The pen has the advantage that you can fidget with it in public and no one looks at you funny like they would if you were flipping a knife. Let me know if you have any questions.
