There is shockingly little information on the hammer and sickle symbol available. Obviously the hammer represents toe workers and the sickle the farmers, but other than that there isn't a lot. I did find out that Sickle is a company that sells rock climbing clothes. Seems like every rock climber I know wears whatever crap clothes they have on hand and usually look like they just got back from Burning Man (that last reference was crowbared in as a nod to my good friend John). I guess I don't hang out with the right kinds of rock climbers. Also , Hammer Films is a company that does some b horror movies. The site is well worth checking out.
All prices are in USD.
