Unbreakable Walking-Stick Umbrella U-115 (Crook Handle)
The original Unbreakable Umbrella, handcrafted in Poland by inventor Thomas Kurz since 2004 and endorsed by Dog Brothers Martial Arts — the organization that tests gear under full-contact live combat conditions. The fiberglass and polyamide composite shaft is structurally equivalent to a steel pipe while weighing under 2 pounds, supporting 140kg (310 lbs) of axial load. The 12mm stainless steel tip and crook handle are optimized for the stick-fighting grip patterns taught in Kurz's accompanying instructional materials. It is completely legal to carry anywhere umbrellas are permitted — airports, courthouses, public transit — because it is, functionally, an excellent umbrella. It also happens to be one of the most effective legal self-defense tools available.
