Test report (download PDF) comparing commercial and experimental
one-handed springlock systems, including the new SurMount Cordloc from ITW
Nexus and various new systems that I developed over the years. The tests
show, among other things, that some commercial springlock tethering systems
are much less effective than others for one-handed operation and that the
new systems proposed are more effective than the commercial ones.
Instructions (download PDF) for do-it-yourselfers interested in making
their own improved one-handed springlock tethering systems for jackets,
backpacks, etc..
