I bought one of these Lucky Line Flex-O-Loc , 5", Assorted Colors; 1 Per Card (71101) https://www.amazon.com/dp/B000JQ05B4/ref=cm_sw_r_cp_apa_b2Y3zbAC6DEQB back in june 2013 after becoming a fan of /r/edc and its never came apart on me because its 'deform to unlock' rather than 'twist to unlock'. When i bought mine it was only $2.96 including shipping from 'aj wholesale' on amazon, now that amazon sells it themselves at retail pricing the price has gone up.
Attach a bell. Some of the tracking hounds I've hunted with in the woods get a 1" toy cowbell attached to their collar with a Lucky Line-style keyring.
it's a high-quality aircraft cable. got it from amazon:
the picture shows a blue example, but you'll get a red one.
Get a couple of Flex-O-Locks and never deal with manhandling a key ring open ever again in your unnecessarily long life.
I use the Lucky Line keyrings <http://www.amazon.com/Lucky-Line-71101-Key-Ring/dp/B000JQ05B4/>
I've switched to these key rings and love them: Lucky Line
I was actually thinking the cable was this kind I didn't realize it was the screw off type.
when you get tired of that keychain working itself open, check out one of these - http://www.amazon.com/Lucky-Line-71101-Key-Ring/dp/B000JQ05B4
I had one that came undone all the time. Used to drive me crazy. I bought one of these key rings on a whim and it really has held up - has yet to accidentally open on me: http://www.amazon.com/Lucky-Line-71101-Key-Ring/dp/B000JQ05B4
ive had one of those bust when I took it out of my pocket and I nearly lost my keys on a train. I use this now.
I'm a big fan of the Lucky Line Flex-O-Loc.
