This is the Akimbo

I love the look of this device and would buy it with or without a spring (on the BDB right now myself). However I would agree with Rich on the spring if it can be incorporated and doesn't cause ant patent issues. Having the spring does not cause any real issue other than possible laziness about checking yourhitch before you sit back. A spring like what is on the RR made by a reputable manufacturer probably has at least a million cycles to failure and are not that expensive for the extra piece of mind.

The spring for self engagement is a critical life support component.

so what are your feelings about the bone? I have never had it not engage in over a year of use at this point. I don't see the spring as necessary if the device is not designed around it being necessary. Hitches well tied or not are unpredictable. I always had to check that they engaged. Not a concern with the bone, or the runner, but moot point there.

I do agree with you on this, but only to a point. The danger of climbing on a tool that
has a relaxed, frictionless position is extremely dangerous. This has been proven over and over as climbers keep striving for the " holy grail " of self- tending.

I personally find that a small amount of contact friction is more beneficial than not. As this new tool is still in the design stages I would prefer to see this contact incorporated into the works and not rely upon a spring as essential to its function. It would be best if Jamie could relegate the spring to just a performance enhancement as opposed to a critical and life dependent component.

Something needs to maintain a consistent and light pressure over an inconsistent surface to provide the friction needed to self engage the device.

I feel confident in judging a piece of textile and most hardware for serviceability. How do you know when a spring is about to break?

The same way you would decide if your bollards, rings or biners were okay. You touch them, feel for abnormalities and have faith in the manufacturer. Other than that not really anything that the average guy is going to do on a daily basis.
 
there will be a spring on the Akimbo. if the spring were to break, the Akimbo would not fail to function. because of the adjustability built into the design, it is possible for a new or untrained user to set the top arm too loose and experience less than ideal performance. a spring will hopefully limit that possibility.
 
I don't have any idea what the legal terrain is like, from the first taughtline I ever humped up on, I knew that my life support was my responsibility. As a heavy climber, I when I tie a friction hitch, it is frequently an "expert use only" knot that barely engages and which I would never allow a new climber to use. I think this is very similar to the difference between the regular Rock Exotica biners and the ORCAs.

does the runner fall into the big top multicender category? The spring does not prevent an object from depressing the bird. And the hitch hiker, or any other cordage can be depressed by accident as well. It's just harder given the relatively small profile. There is no way to prevent that from happening beyond being a careful and observant climber.

Yes, I would put the RR in that category. Totally agree, nothing prevents it from happening and that is not what that spring on any of these devices is intended to do. Think of it as a self starter, not prevention. A hitch cord can do the same, just not easily. I see people put a sliding ball above the hitch to make it easier to operate, that would make it a "bigtop" to me.
...and I agree, the spring does not PREVENT an object from depressing the bird, the spring just starts the engagement of the friction component without action from the climber.
Anyway, sounds great that the Akimbo will have this.
 
I have not looked closely at the "why" of the design of the Bulldog Bone. Can anyone answer why it is that the Bone seems to not need a spring? Thanks in advance.
