Popplock T6

The Popplock T6 is the latest trick lock to be made by Ranier Popp. This review is a little special as it’s the first video puzzle review I’ve done. Things are a little rough round the edges, and if you like it, then I’ll do more, and hopefully they’ll get better over time.

Despite what I say in the video, the rivets are copper, not brass. Sorry.

The T6 is 1.5″ square and comes in two different versions. A copper riveted version, and an aluminium riveted version. The mechanism for both is the same, and it’s only the external appearance which differs. Personally, I really liked the copper look so decided to get this version for my collection. An interesting note is that the direction the hasp opens is mirrored between the two versions. You can see the differences on Ranier’s site here. I bought mine through Wil Strijbos, and jumped on the chance when he mentioned he had some available. They are also available currently from Puzzle Master.

The lock is constructed from stainless steel and as a result is fairly heavy, and very solidly built. There’s no worry about damaging this lock if it’s dropped, or passed around for people to play with. The key supplied looks to be brass (some of the silver plating on mine has rubbed off) so you know they key is solid too, and no chance of it breaking, unlike some early Popplocks where the keys weren’t so robust. As you’d expect all the tools you need to open the lock are included, no paper clips or acetylene torches required.

The back of the lock sports the familiar feline Popplock logo engraved into the lock, and the copper rivets mirror those on the front.

I freely admit that I’m no expert on solving trick locks. This is the first Popplock I own, and only the second trick lock in my collection. I took a fairly systematic approach to the puzzle, poking and prodding the rivets and anything which may not be as it appeared before putting the key in the lock and turning it. The movement of the key in the lock is very smooth, and there’s no real feedback turning the key in either direction. Not to mention that turning the key in either direction doesn’t open the lock! I can tell you’re surprised by this news.

Fairly quickly I noticed that there are two levels the key can be inserted at, and two ‘discs’ inside the lock which the key turns. The key can only be removed when the top disc is back to its starting position, but the bottom disk can be left at any point. Turning the key you notice a small notch in the upper disk. Surely that is important. Investigating further I found a similar notch in the lower disk and also a dot on the disk. With these reference points, I started to get a feel for what was required to open the lock, but I still had no idea how to execute it.

It took around two hours and a lot of trial and error to figure out how to open the lock, and all I can say is that it’s a clever yet simple mechanism. The mechanism is very cleverly disguised and really requires you to examine everything and assume nothing. As Ranier Popp states on his website, it’s not easy to solve. I highly recommend this puzzle, and if you’re new to trick locks, or to the Popplock series, this is a great puzzle lock to own. I may have to hunt down the rest of the series now!

    I am glad you enjoyed it – I got mine today and solved it too. I think I went through the same process as you. I also struggled with the final unlocking motion – pretty clever really!

    Good luck getting the other Poplocks! They are mostly unavailable now and the one that you can still buy is about $350!!! I also would love one but that is a whole lot of cash which I don’t have!!
