I’ve been using a Hammerhead Gear Keeper retractor at work for many years, but the cable is nearly frayed through, so before replacing it I wanted to know if there are any decent alternatives that need considering first? I’ve been happy the Gear Keeper, no issue there, just wondered if something else cool had appearedĀ 
Lots of cheap and nasty ones turning up in my searches, but want something robust for about 5-7 keys.
Thanks for any advice,
Patrick
