Originally I thought these darts were Voks due to the spring loaded point. As it happens, tho, they probably are not. One person at Dartsnutz.net believes they are Steve Beatons and this was seconded by someone who was selling a set on ebay and listed them as
"MEGA RARE 23 GRAM ELKADART STEVE BEATON SPRING LOADED TUNGSTEN DARTS".
I don't know for sure but I am willing to go with that. Of course, if something is listed as "mega rare" on ebay, that means it most certainly is not. Still, other than my set, this is the only set of them I have ever seen.
As they are currently configured, they are wearing their original spring loaded steel tip point and medium length, standard condor stem-flights.
