Pivot Bushing

[TimmyBoston]

Are there any other folding knives, besides the Chris Reeve knives that use a bushing around the pivot?

Thanks

I was just thinking about asking the exact same question.

So are there any other knives like that where you tighten it all the way and it's perfectly smooth?

I was going to post exactly the same question as well... Scott Cook's Lochsa is the only knife I know of off hand with a Sebenza like pivot bushing. Limited production makes is nigh impossible to get one.

Spyderco has adopted a bushing system or sorts on some of their knives, from what I understand. I know my Manix 2 has one, as I took it apart.

The Buck 110 uses a similar bushing.

Striders have bushings also if I remember right.

What do you mean by bushings? As in bronze phosphor washers or something else?

Here's a thread with a photo showing the brass bushing inside the blade in the second post:

There's been a lot of confusion on this issue. A lot of people think the "bushing" in this context means a washer. It does not. It's a barrel shaped bushing made out of steel in the Sebenza, or brass in the 110, that fits insude the blade bushing/pivot hole. It extends slightly outside the hole on both sides by a controlled amount. In the case of the Sebenza, the distance is so closely controlled that there's no need to adjust the pivot screw -- in fact it's not adjustable. Similarly, in the Buck 110 the amount of protrusion from the blade is meant to allow the blade to open but not allow noticable play.

Here's a link to a thread on Sebenza disassembly that shows the bushing:

The EDI Genesis, now discontinued, used a Sebenza type bushing, but it was nowhere as precise as the Seb!

They don't.

However Spyderco has started using it on several of their designs, I believe the Leafstorm uses the pivot bushing.
