Osprey Pens is offering Size 6 special grind nib units compatible with Pens that accept JOWO nib assemblies. Available in Broad -Stub, DoubleBroad -Stub, Architect Broad, Architect Double Broad, Broad Left-Oblique, Broad Right-Oblique and Zoom DoubleBroad (BB)

These Nib Unit work with pre-filled ink cartridges or with bottled ink using a converter (any generic international converter/cartridge will work with this threaded insert).

Stub: A Stub nib tipping material is ground flat on the end. This type of a nib produces a narrow line on the cross stroke, broad on the down stroke. It mimics calligraphy (without doing anything different!) unlike flex nibs, which require pressure to change the line width. A stub nib is (usually) a broad nib that has a flat end but smoothly rounded corners. Available in Double Broad and Broad.

Architect nibs are opposite to Italic nibs. They give a thin downstroke and a thick sidestroke. Also known as Hebrew grind. Designed for sharp, straight lines, this nib works best for print style, when writing in Roman letters. The line variance is enormous. Typically, not used for cursive writing. However, if you want to be adventurous, and love experimenting to get fun print letters, or other artistic explorations, this nib can be useful.

Try using a consistent writing angle to reach its full effect.
Comes in Architect Broad (up to 1.2mm stroke) and Architect Double Broad (up to 1.5mm stroke)

With a Zoom nib, line variations depend on the angle at which it is held, low angle gives thick lines, high angle (almost perpendicular to the paper) produces fine or thin lines. Good nib for sketching as it generally writes wet, especially for someone that likes medium to broad strokes. Flipping the nib to get thinner lines is always fun! From changing the angles from 15 to 45 to 90, you can get thick to medium to fine lines, which means you can almost get 3 different nib point writings with this one nib!!

Oblique: An Oblique tip is where a conventional rounded tip (like in a Standard Size 6 Broad nib as an example) is ground flat at an angle of 15 degrees. If the angle is made from top right to lower left, the nib is a Left Oblique (think of the shape of your left foot and hence also called Left-foot Oblique), and if the angle goes from top left to lower right then it’s a Right Oblique (also referred to as a right-foot oblique) nib.

Left Obliques are most comfortable for right handers. (NOTE: Right-Oblique is more comfortable for LEFT-HANDERS). Expect the line widths to be more subtle. The rotation of the pen in the fingertips is key. If you are right-handed, rotate the grip section (and thus the nib) towards your thumb. This position keeps the flat edge of the nib properly on the paper as you write. Similarly, if you are left-handed, rotate the grip section (and thus the nib) towards your pinky finger.

When using a right oblique, reverse the grip position by rotating to the right.
(Note: Osprey obliques are normal round tipped, and not italics.)
