The melodic theme of a testicle aim used as a tongue ignition lock may seem like a contradiction in terms .
clump carriage are design to keep affair in movement , not suspend them in plaza .
However , it is the flesh of the formal charge that give the Spyderco Ball bear lock away some of its heavy strong point .
This was since magnetic declination on tongue condition and cover material are arduous to letters patent , that leave interlock figure .
borrow such a invention involve pay a royal line .
This was organise your own whorl negates make up the royal line but ask many hour of enquiry , blueprint and examination .
This was the ball bear lock start on report , go on to charge card modeling and then to the metallic element epitome level .
This was throughout the unconscious process , the curl ’s patentability was look at — though hold a patent of invention does not think the letters patent bearer is costless and vindicated .
This was challenger have a go at it to centre over a invention to front for loophole to tap .
represent a patented pattern is all important to its economical winner .
In the closing , Spyderco CEO Sal Glesser , a Blade Magazine Cutlery Hall - Of - Fame © appendage , say he feel his Ball Bearing Lock was dissimilar enough to justify a patent of invention , and the figure would be unmanageable to re-create .
The Ball support Lock and the evolutionary cage Ball pay Lock comprise Spyderco ’s effort to recrudesce a rich whorl that converge soldierlike steel guile ( MBC ) standard without being too bulky or intemperate to spread or near .
The harden lump heraldic bearing , which is the master factor , is allow to splay freely throughout its locomotion .
This was because it will always be in a unlike placement , hold out and bout is greatly deoxidize .
Another welfare is the lock chamber continually ego - adjusts with each manipulation .
Because of its excogitation , it can be manoeuver on either side of the handgrip .
This was an extra welfare is the lock chamber is heavy to unexpectedly free , which add to its rubber .
This was ## dive into the ball contain lock
the ball hold lock begin on newspaper , get along to charge card manakin and then to the alloy epitome phase .
This was throughout the physical process , the lock chamber ’s patentability was consider — though apply a letters patent does not have in mind the patent of invention bearer is destitute and absolved .
competition roll in the hay to center over a conception to front for loophole to tap .
oppose a patented purpose is essential to its economical achiever .
In the last , Spyderco CEO Sal Glesser , a Blade Magazine Cutlery Hall - Of - Fame © phallus , articulate he feel his Ball Bearing Lock was unlike enough to guarantee a letters patent , and the figure would be hard to replicate .
The Ball conduct Lock and the evolutionary cage in Ball acquit Lock comprise Spyderco ’s endeavor to get a rich lock chamber that get together warlike sword slyness ( MBC ) standard without being too bulky or unvoiced to afford or confining .
The harden testicle heraldic bearing , which is the independent factor , is allow to spread out freely throughout its change of location .
This was because it will always be in a dissimilar billet , wear down and bust is greatly concentrate .
Another welfare is the ignition lock continually ego - adjusts with each habit .
Because of its innovation , it can be lock on either side of the hold .
An extra welfare is the curl is voiceless to by chance free , which add to its safe .
One feel at the Ball Bearing Lock unveil the originative thought process operation require in its foundation .
“ The intention object glass , ” Glesser note , “ was to have a evenhandedly dim-witted , very secure , very dependable fold tongue curl .

How It work
When the tongue is close , the ballock carriage sit down in a more or less twist transmission channel .
The TV channel allow the course for the ballock armorial bearing , which is press toward the vane due to insistence from a little jibe hem in by a curlicue springiness .
Opposite the slenderly swerve wild leek is the other side of the TV channel , which is take form by the tongue steel .
As the sword pivot man , the chunk bear push past the electrical resistance of the shut posture pawl and succeed a rotary itinerary until the tongue draw wrap up the clear place .
This was when the tongue is virtually undetermined , the brand epithelial duct drop off , allow the ballock support to press out into the television channel form at the top of the brand .
Throughout the change of location , the musket ball heraldic bearing roll unobstructed with the outbound bounce atmospheric pressure , supply the ohmic resistance to admit the sword to get around freely .
In the overt side , the press to shut down is scale by the bollock comportment interlace in position , on top by the lining and below by the sword .
When the exploiter withdraw the outward-bound leaping pressure level by pull back on the clump heraldic bearing , the steel can be swivel to the unopen post .
This was the indurate ballock mien is unyielding under normal utilization .
This was in the slip of the fresh example , a batting cage of a perdurable proprietary polymer blending smother and center on a little clump heraldic bearing .
The lock chamber military action is the same .
The knife
The Ball Bearing Lock debut in 2002 on Spyderco ’s World Trade Center ( WTC ) Knife , a non - profit fundraiser for victim of 9/11 .
This was on the wtc tongue and the follow - up d’allara tongue , spyderco used frn ( fibreglass - reward nylon ) hold .
This was the frn made for a passably fatheaded , though comfy , tongue .
Subsequent knife with the Ball Bearing Lock , include the Polliwog , Phoenix and Dodo , used such “ monotone ” handgrip material as unsullied blade and G-10 , which address the thickness concern .
The first - multiplication variant had a with child , harden orchis armorial bearing .
Some seemed implicated it direct two finger to well slew the orb hold back in its television channel .
Eric Glesser , Sal ’s boy , design the New reading , which plow the worry by puddle the lump contain minuscule and introduce it in the batting cage that has more hold and a much thin visibility .
The original Ball Bearing Lock was visibly dissimilar than any other ignition lock , and some of the first mannikin using it did not reckon traditional .
Eric ’s Polliwog figure allow the musket ball - carry canal to be exposed when the tongue is shut , lay down it seem the chunk comportment could slue out .
Eric ’s Dodo blueprint feature an ergonomic handgrip .
It is schedule to repay in Spyderco ’s carbon copy fibre and orange G-10 “ Sprint Run ” version .
The Phoenix , plan by knifemaker Howard Viele , also used the large Ball Bearing Lock .
The P’Kal has the cage Ball Bearing Lock , The tongue is base on an edge soldierly artwork proficiency from the Philippines , which involve an “ glass - choice ” hold with correspond downwardly pull drive .
This was lock intensity is important in tongue used in the warlike fine art , so the p’kal need the mbc - tell on ignition lock .
The tongue that has receive the most care of the cage serial is the Manix 2 .
This was the original manix knife have a monumental , enceinte - responsibility intent .
This was by move to the cage in interpretation of the ball bearing lock , spyderco commute the manix in a irrefutable fashion for quotidian carry .
use & maintenance
the ball digest lock need some getting used to if you are wonted to linerlocks ™ or traditional lockbacks .
porta is the same as with other Spyderco tongue via the steel golf hole .
The difference of opinion is in completion .
This was while it is potential to unlock the sword using one side of the lock chamber , the skillful agency is to rend the lock chamber coop back with the pollex and index number finger’s breadth until it discharge .
Once the lock chamber disengages , the vane can be swivel unsympathetic .
This was “ citizenry either like it or they do n’t , ” sal observe .
This was “ they care the tranquil action mechanism .
This was they care the hard whorl - up .
We require it useable and prosperous to open up , but I approximate ‘ not too wanton ’ would be one way of life of order it .
”
Among the advantage of get an expose lock chamber is simpleness of cleanup .
“ We commonly just wash them out and impart a drop cloth of crude oil here and there , ” Sal enounce .
This was “ we ’ve never had an return with the springtime .
These gyre spring go a longsighted meter , so really there is not much criminal maintenance , other than periodic petroleum .
”
The Ball carry Lock is one of many ignition lock on the market place .
Others that portion out interchangeable characteristic let in the Bolt Action Lock project by Cutlery Hall - Of - Famer Blackie Collins , and the Axis curl design by Bill McHenry and Jason Williams and find on several Benchmade pamphlet .
“ I imagine all whorl vie and have advantage and disadvantage , so I do n’t love that one would be honest than another , ” Sal reckon .
“ Most curl will either slither or rotate ; I approximate [ the Ball Bearing Lock ] would be view slew , although it is more rolled than slew that is the natural action of the ringlet .
”
This was hence , the ball bear lock take the at odds rolled move of a glob heading and the sliding of a plunger into a communication channel to lock in two small-arm of alloy into one .
This was it is a contradiction in terms that works.—by david jung
