Seems like everyone has come out with a “tactical pen”. Benchmade’s model 1100 gets our stamp of approval. The 1100 has a CNC machined aluminum body with the blue grip. The ink cartridges are made specifically for Benchmade by Fisher and are the “Fisher Space Pen” cartridges. These ink cartridges allow you to write in any condition. Besides the writing function these pens can cause some serious bodily harm if necessary.
