bout the Nuptse:
The Nuptse (pronounced "Nep' tuse") is named after the Nuptse mountain in the Jhumbu region of the Mahalangur Himal, in the Nepalese Himalayas. It lies two kilometers WSW of Mount Everest. Nuts is Tibetan for "west peak", as it is the western segment of the Lactescent massif. The summit of Nuptse is extremely dangerous due to loose snow with a lot of hollows, and there are also weakly attached cornices of snow. This provides a barrier to climbing, yet is not sturdy enough for safe climbing. For more information about Nuptse mountain, visit:

Nuptse Style and Dimensions:
This pen is similar in style to the NAZCA. It was first made as a special order and re-sized from the original NAZCA. But although the overall shape looked much like the Nazca, it's shorter (6") and it didn't have that hallmark TALL finial anymore. It was suppose to be a JR, but didn't have the Jr clip either. So after getting additional requests for the pen, I decided to break it out and give it it's own name. The most prominent feature of the Nuptse is the multiple accent bands placed throughout the pen. The pen has a overall length of 5.75" to 6" depending on the number and layout of the cap bands. The pen can be ordered with the bands in multiple configurations, and with your choice of standard clip finishes (24k gold, chrome, or Gunmetal (aka black chrome). It comes fitted with a#6 nib in your choice of finishes. Nib finishes available for STEEL nibs are: 2-tone, polished steel, Black Oxide (#6 only), or Ruthenium (#5 only). Current tip sizes are x-fine, fine, medium, broad, and two italics (1.1 both; 1.4 for #5 only, and 1.5 for #6 only). 14 & 18K Gold nibs are also available as a special order.

Nuptse Options and Upgrades:
Since the Nuptse is already loaded with accent bands, it doesn't require any hardware upgrades. But you could upgrade it with a custom inking system such as a piston or button filler. While the standard Nuptse is made as a cartridge/converter, the blind cap made to install the band on the end of the barrel is threaded, and it can easily be drilled out and fitted with the parts for a Button-filler. You also may want to consider adding a 14k or 18k gold nib.

I also offer a variety of hand-made Pen Props and Pen Buttons. You can order a Pen Prop in a material to match your pen, or any one of the wooden styles made in a variety of stained or dyed colors. The Pen Buttons are available for any of the clipless pens.

About this Pen and Material:

The material used for this pen is a custom mix of acrylic from a supplier by the name of Bob Dupras. Bob makes his own material and uses it for his pens, but he also sells it. I wasn't aware of Bob and his material until the customer requested it. I was sent an image of another pen made from it, and was ask if I could get it. So not knowing where it came from, I had to do a little investigative work to track it down. It turns out Bob has quite an assortment of material with more than 50 colors in his inventory, so I may get the opportunity to use something else of his in the future.

This particular color is called Ocean Cenote. If you're not familiar with a 'cenote', it's a deep, water-filled sinkhole in limestone that is created when the roof of an underground cavern collapses. When the cavern collapses, it creates a natural pool which is then filled by rain and water flowing from underground rivers. And if you do a search of the term, you find images of cenotes that have very similar colors as those used in this material.

The blanks I received did not appear to show any defined pattern in them from the outside--they looked more like the colors were simply blended together in the mold at random. But as I inspected the blanks more closely, I noticed that some were dark at one end with dark blues and greens, and then brighter colors on the other end with copper and a lighter green. So I took a chance that maybe the colors shifted from light to dark transition along the length of the blanks and decided to use that in the design. I planned to orient the blanks so the lighter colors would be in the center and the dark colors out at each end. If it turned out the colors were mixed randomly without any pattern to them, then it wouldn't matter how I oriented the blanks. So at least this plan could take advantage of the pattern transition if their was one.

I started out by making the barrel first, and used the lighter end of the blank (with the copper) for the threads. As I reduced the blank to size, I was able to see that the colors did shift along the length and transitioned with the dark colors (blue and green) at the blind-cap. Mixed in on the upper side of the copper (opposite the darker colors) was a brighter green. So for the Section I decided to cut a piece from another blank that had the copper fading into that green in order to complete the transition of all the colors. Then when it came to the cap, I reversed the color transition and started at the base of the cap with the copper so the base was the same color as the threads on the Barrel, then would transition up to the Finial with the darker green and blue. The result was sort of a star-burst pattern radiating out from the lighter colors in the center of the pen out to the darker colors at the each end with a surprise of the bright green on the Section when you uncap the pen. I think the end result turned out pretty well after just starting out on a hunch!
