If you like good pens and aren't buying a twosun, you are probably spending more than you need to.

As a poet I can say arguably the three most important aspects to a good pen are ergonomics, writing quality and if you find it attractive. This is beautiful and ergonomic. I am very particular about my ink and how it dispenses so I almost never keep the original ink cartridge and replaced this one as well.

I'm sure it could be used in a tactical situation though the rounded end cap seems ike it would be less prone to positive control than a flat cap.

I didn't buy this for its tactical quality. If I did, I would give this a 4 out of 5. As the shell of a very nice writing implement, I give this 5 out of 5 stars.
