  1. I realize that this is really old stuff but… If you read the reviews via Amazon a lot of people complain about the key breaking off. Somehow I don't think that is a very good application for a disc detainer lock. Rain, corrosion, dirt and some of the keys for disc locks I've seen are quite weak where the actual bitting is done. If you still have some keys around it would be interesting to know how easy it is to twist one off…

  2. I've got a question about staying safe, I would like the communities opinion on a decent bike lock, reasonable security and with keys that can be duplicated. I would prefer a cable lock, but I realize that they aren't too secure.

  3. You know what works faster? Liquid nitrogen, or similar super-cool fluid, and a small hammer on the hardened steel 😀 Or heating up with a relatively weak torch, then hitting it with liquid n2… even more fun, like cracking a mug by putting hot coffee in, and then ice water right after…

  4. It's nice to see that when a product from a company that you know to make a large majority of garbage actually tests to be "not the usual garbage", you give credit where credit's due!

  5. +bosnianbill hello,I got a smaller one with chain (rated 9/10 master BScale), and I would like to know if the disc detainer is somewhat useful? (the locking thingy is a lot bigger on mine)

  6. hey bosso i would like to stay legal but possession with out a locksmith licence in my state is illegal (to the best of my knowledge), but i will defiantly try to stay safe. thanks from the AU for the great videos!

  7. I think these locks are bottom tensioning. I took an early model of these to a bench grinder back in 09, and took the cylinder out. The steel guard/face plate in the front had a tight warding design that kept me from making a effective tool for it though. The front plate on the newer ones are much wider I think.

  8. Hmmm, I wonder how well a hydraulic jack would work for a slower albeit more quiet entry. Would the slow force eventually shear off the locking tabs or just bend the shackle?
