The ultimate connection between string and arrow...
... is a ball
As early as the 1990s, the idea emerged to accelerate the arrow optimally and without error by means of a ball nock.
The superiority of a ball’s geometry, whose shape is reproduced 1:1 by the nock bed of the ball nock, should be evident to everyone – it represents the ideal and unsurpassable way of transferring power from the string to the arrow shaft.
While the first experiments back then began with plastic balls, over time — originally developed by Ambo — an optimal final product evolved: the brass ball, later designed as a pivot ball.
The advantages of a spherical nocking point are clear:
-
Perfect axial force alignment for optimal shaft acceleration
-
Constant power transmission through the pivoting, tilt-free interaction between nock and pivot ball
-
Identical slip over 360°, meaning absolutely consistent release resistance, even with different string twists during the draw
-
Completely symmetrical shape, ensuring no loss of static balance
-
Clearance angle of over 80° – the nock maintains contact with the ball at all angles and cannot accidentally unclip even when the bow is fully drawn
-
The center serving is no longer stressed by the nock – wear and inconsistent nocking behavior are now a thing of the past
Time for Ball Nock 2.0
A solution as perfect as the ball nocking point deserves a modern version of the matching nock – both in construction and appearance.
We are proud to present the improved evolution of the Ambo Ball Nock:
the EVERTS Pin Ball Nock.
It stands out through:
-
A completely new, CAD-generated, optimized design
-
Ultra-precise fit, with significantly reduced play between the nock and the ball
-
Highest dimensional accuracy, ensuring all nocks are exactly the same size thanks to state-of-the-art manufacturing processes
-
Consistent slip, meaning a constant release force and thus the same acceleration power shot after shot
-
An even greater and unmatched clearance angle compared to any other nock on the market
-
10 carefully selected colors, developed in cooperation with experienced archers and professional dealers — 7 of them made from clear material, allowing you to detect even the smallest damage early and replace the nock in time
The very short nock wings ensure a lightning-fast separation of the ball and nock, without any lingering lateral forces from the string.
This means the arrow experiences much less lateral tuning effect, allowing — or even requiring — the use of a softer arrow.
Important for archers:
Shooters who choose the EVERTS Ball Nock System should know that they usually need to raise their nocking point by about 1–2 mm.
Here, too, the golden rule applies:
Every change in material requires fine-tuning of all components.
The pivot ball fits perfectly for 14–20 strand strings, based on BCY 8125 string yarn.
If you prefer a tighter fit of the ball on the string, you can reinforce this area with a few extra strands of string or center serving thread.
Experienced dealers can build your complete string with integrated pivot ball — and they also supply the EVERTS Pin Ball Nocks.
