Info on Shot in Dark –
I have the spark knives from these guys. They are basically set of knives cut out of steel and handles wrapped in metal cord. You have a set of gloves that have contact points in the palms that are wired to a 12vdc power pack in a pouch. This is stored in a gut belt with some suspenders. They work great. We used them every night in our haunt and they had a great effect. I bought them right off the show floor at Transworld for I think $350. I'm happy with the product and would recommend.
