We've Gone Metric Baby.

American Made Stainless Steel Pivot Replacement Set of 2 for 4mm Balisong Butterfly Knives from Asia.

FOR USE WHEN USING BEARINGS OR LINERS OR THICKER HANDLES OR THICKER WASHERS ON EXILED CUTLERY SANDWICH MODELS

Tired of Junk Hardware, Then Let American Hardware Solve The Problem.

I have redesigned pivots with an open HEX back so you can use an Allen Head Key screwdriver to firmly hold it in place while you tighten and set the screws, this makes things simple and efficient and easy to adjust and remove.

The Slotted ones were good but a bitch to hold and with the 90 degree of an Allen Head Key it makes life so much easier.

Then ECC one up'ed this shit with leaving the back open for a hex head set screw to tighten against the 10mm M3 screws installed from the other end.

Pure Fucking Genius.

Ok, Asian Hardware SUCKS !!!!

The Asian Made Balisongs Are Alright But The Hardware Is JUNK !!!!

Fits into 4mm hole mounts.

MADE IN THE USA

I had these custom made in Colorado, so these are high quality nothing but the best.

The barrel pivot has an allen opening on the head to hold it in place while threading the screw from other side. The barrel pivot also has an increased diameter to press fit one side into the frame if the face is correctly bored, making the screw hold while tightening the screw on the other side.  The set screws provided in this assembly are inserted to thread opposing the self sealing screw through the center of the allen socket on the barrel pivot head to provide opposing force against the inclined planes of the threads providing a locking force between the screw and the barrel pivot.

This also stops the pivot screw from un-tightening from pivot spin.

The assembly comes with two M3 pitch screw screws.

The assembly comes with two M3 screw set screws that insert through the barrel pivot opposite the the main screw.

Modifiable for Replacement Retrofit Of Many Existing Balisong Butterfly Knives
