The main update is a needle bearing that makes the rotating part very
very smooth to operate and thus the feedback from the lock is very
The other is that the feeler rod that used to get broken easily is now
made from hardened and nitrided tool steel that has been carefully
ground to proper size. This makes it virtually impossible to break in
Third update is the ability to change all the parts, especially the
tensioner. All parts are held together with screws, so I can make
special sizes per request (though with a longer lead time). Also the
feeler rods are available in many different sizes, though smaller ones
cost more and anything other than 2.5 mm diameter takes more time.
Also the screws that attach everything together work as places for
fingers to turn the pieces so that it is easy to vary the tension. All
the parts are made from polished steel for durability.
And because of all the screws, it is easy to change the orientation of
the tensioner tip so that your fingers are in a nice position when
tensioning the lock.
