The site How Stuff Works has an excellent video of brick chisels being made at Baltimore Tool Works, which closed in 2009. The lack of automation is typical of older forges, making this video a rare insight into earlier manufacturing processes.
All types of brick chisels should be sharpened with a flat bevel, as on a sharpening stone or a belt sander. The concave surface or hollow grind made by a grinding wheel makes a thinner, weaker edge.
