Hand forged from 303 stainless steel to resist corrosion

Diamond cross section comes to a pyramidal point
Hand filed to break edges on the corners for additional grip comfort
On the Black Quills, these feature a dark surface finish formed by rapid oxidation of hot steel exposed to air--a form of iron oxide. This finish is far more durable than a chemical patina. The dark surface finish is removed on the pyramidal tip, chisel edge, and top corner of the Quill's diamond cross section (which is used for scraping tasks).
 
Quill sizing:
Put your middle and ring finger together and measure the circumference around the widest portion.
If this measurement is less than 4", choose the Slim Quill size.
If this measurement is between 4" and 5", choose the Original Quill size.
If this measurement is over 5", choose the Quill XL size. However, smaller sized hands can still use the Quill XL, it just requires an extra finger to grip through the hook gap portion.
