Any impact, including a helmet dropped from a moderate height, can compress the inner liner in ways that are not visible from outside. A helmet is designed to absorb one significant impact by sacrificing that inner material, so a helmet involved in a crash should always be replaced, not inspected and reused. A handcrafted helmet shell starts with a base material, commonly fibreglass or a composite blend, layered and shaped by hand rather than produced purely by mould and machine. Each layer adds strength, and the shaping stage is where a lot of the time in production actually goes. This is slower than fully automated manufacturing, and that is the point. A handcrafted shell trades speed for a level of finish and individual attention that a purely machine made helmet does not offer. The liner deserves the same care. A removable, washable liner keeps the inside fresh, and following the maker's washing instructions protects both the padding and the stitching around it. A made to order helmet starts long before any material is cut. Measurements are taken, the intended use of the helmet is discussed, and a rider works with the maker to settle on a shell, lining and finish that suit them specifically, rather than picking from fixed stock sizes. Full face and open face [[https://rentry.co/91289-handcrafted-in-london-the-story-behind-a-helmet-workshop|Hedon Helmets]] suit different kinds of riding, and the right choice usually comes down to where and how you ride rather than looks alone. A full face helmet covers the chin and jaw, giving more protection in a wider range of impacts, and tends to suit faster roads and longer distances.
