It used to be that a gentleman could arm himself with a sword cane, ready to whip his blade out at the first sign of unseemliness. Since parliament has banned anything that may be sharpened to a point, defense of oneself has become a more subtle skill.
Some gentlemen learn the unarmed arts, but in the face of villainy, stronger means are occasionally required. Hence the Umbuster, an umbrella combined with knuckledusters.
After some few years the non-product continuously known as The Umbuster has formally graduated from solid-world prototype to a bespoke-produced and purchasable boxed goods. Each handle is individually CNC cut in a 5 hour process by the enduring Mr Liu. The umbrella itself is provided by the good Guy de Jean of France. And finally packaged in the boxes designed with the good Snorri Már Snorrason here in Reykjavik Proper.
At €225, it's not for dilettantes. A firm drilling at your local Baritsu academy prior to deployment is strongly recommended.
