Zak Tool Knurled Flat Grip Swivel Key
ZT9PRegular price $8.99
ZAK makes good stuff, I have used a lot of their cuff and key tools over the years. This little guy works just fine... but it's a hair snug on Peerless cuffs. Nice an smooth on SW cuffs but it hangs up a tad on the Peerless. Still works fine but the key tab could use a few swipes with a file to make it work better. Lifetime warranty too.
