Yes, this is a direct copy of Shawn Newton's Shinobi, which was designed by one of his customers. https://newtonpens.c...lluloids-small/
The Shinobi is made in several sizes, and many materials (disclosure, Shawn built one for me). It can cost upwards of $300 depending on your choices.
However, the Shinobi is machined and polished by hand from acrylic or ebonite rod stock--so the strength and thickness is considerably greater than injection molded polycarbonate, which I believe my M2 is.
At 10mm diameter this new Moonman is akin to the very smallest Shinobi made--two sizes down from the Small size. And considerably smaller than the M2, which is almost 14mm at the widest point of the barrel (and not the hugest pen itself). 10mm is the size of those small Sheaffer $1 student cartridge pens from the 60's--an extremely small pen to use unposted. I think the Shinobi works much, much better in oversize models.
While a popular design--and every elegant--I should also warn that the Shinobi flat edge is not quite as effective a roll-stop as a clip would be--especially in a smaller size. In a pen of 10mm, I'm not sure that the flat edge would do much.
If someone orders this, can you please post whether the diameter spec of 10mm is correct?
Also--Moonman claims this is their nib--but note that crescent breather hole. Are they rebranding nibs from the Chinese maker of new Conklin nibs? I can't say I've been impressed by the new Conklin steel nibs. The great nibs on the M2 were a breakthrough; let's hope it wasn't a fluke for Moonman.
