Your lockring is solid.  It does its job.  It holds your cog tight through your roughest rides and slidiest skids.  But what about when your lockring needs to take some time off?  Whether it's time to swap in a new cog, a new lockring, or just give your hub some TLC, the Park Tool HCW-17 is just what you need! 

With two different radius hooks it'll fit most fixed gear lockrings (even some BMX freewheel ones) and at 11-5/8" you'll have all the leverage you need to move even the stubbornest lockring from it's post!
