The Bionic Mythos is a HMS carabiner designed to be a workhorse but still be compact.
Instead of the typical screwgate you get on HMS carbiners, Mammut have went with a twistlock mechanism. Simple effective and quick, if for some reason you can’t just wait that extra second or two to use a screw gate.
Utilising Beam technology and hot forge methods, the Bionic Mythos HMS offers a high breaking load capacity whilst keeping weight to a minimum. The Bionic Mythos can cope with a wide range of activities, from multi-pitch rock climbing, to sport climbing, to gym climbing, to classical Alpinism and ice climbing.
A nice bit of kit with a slim, lightweight design, perfect for all occasions, but I feel it could be doing with a safety of some sort. If you want more info check out Mammut.
The Gridlock is Black Diamond’s latest screwgate carabiner. This carabiner is designed to be used as a belaying carabiner. The first thing about this carabiner that catches your eye is its shape. It is more tapered in the centre than other belay carabiners, giving it an hourglass shape. The Gridlock has a screwgate but unlike its rival the DMM Belay Master it does not have a gate clip. On the DMM the Gate clip acts as a double check to ensure you have secured the gate correctly.
The Gridlock does not have this feature, Black Diamond have instead went for a minimalist option in the design of the Gridlock. Instead of a gate clip the Gridlocks screw gate has a tail that faces into the carabiner. When the gate is open the tail moves out the way allowing you to move the rope or belay anchor into the lower half of the hourglass shape. Once the gate is shut, the two halves of the carabiners hourglass shape are separated by the gate tail. This secures the device from rotating between your harness and belay device. The Gridlock has a smoothed top section top prevent rope friction and is generous enough to take 2 ropes.
When all is said and done this is a unique take on the belay carabiner but it doesn’t add any extra safety like the Belay Master, but in saying that some belay carabiners don’t have a gate or a partition.
