This is a PSI Knurl GT pen in black and chrome. It has the stylus tip. I just saw on PSI's website today that they have discontinued the Knurl GT pens. Kind of a shame, I liked the style, and have made quite a few over the years. But Crooked Mill has a copy called Annular, although they don't have as many finishes and they don't have a stylus version. The wood on this one is Thailand Rosewood. I've used this wood a lot in the past, but it's been a while. I just recently ran across this piece. Years ago my b-in-law worked with a guy that had gone to Thailand and shipped back a huge load of it. This is the last piece of what I had. The finish is Pens Plus. I really like the looks of this one.
