Para 2 Detent "Life"?

#1

Post by enduraguy »

I'm curious. With this knifes design, the detent is a major part of the knife. It keeps the knife safely closed for pocket carry. Without it and with how smoothly the blade opens with the bushing pivot, the knife would have to be shelved. Unlike other knives like the Military which do not rely so heavily on the detent. Is there a concern over the longevity of the detent?

Spyderco please make a wire clip version of the Manbug/Ladybug!

Lots of guys open and close the knife 100 times for each time the actually use it. You may be envisioning the wear of cheap unhardened steel then appyling that image to this. But it's a whole other level

There are tons of knives that use a "detent" to hold the blade in the closed position. Some very expensive, sought after, drooled over, lusted after knives, and they all use a detent to hold them closed. It's a "non" issue. All my Chris Reeve sebenzas use a detent to hold them closed. Seen the incredible new Techno? Yep, detent to hold it closed. How about the Sage 1 and Sage 2? Awesome knives. Detented closed. And many, many others. If I haven't made my point, it's this. Don't worry about the detent being a bad design, or failing. :)

Ha ha thanks guys. I had no doubt about the knife, just curious about the detent ball.

Well, they are replaceable. It's likely you will wear the edge to the point it will need a regrind before that happens. Since Spyderco doesn't make replacement blades, if anything I would concern myself with that (but not really).

I have an odd question related to this; is it possible to take out the washer so that the bushing becomes a pivot I can tighten as much as I like?

Disassembling your knife voids the warranty. If you take the washer(s) out your scales will probably scratch the blade near the pivot. Why can't you tighten the pivot with the washers installed? My knives with pivot screws can be tightened all the way from "swinging loose" to "won't open". If you need the pivot screw to be tight I suggest leaving the washers in place and judiciously using loctite on the pivot screw threads to secure it at the desired tension.

I didn't mean the washers between the scales and blades, I was under the impression there was a washer in the bushing or something... I've heard the Para 2 and Manix 2 cannot be tightened to the "will not open" stage due to the new pivot systems.

The pivot bushing is one piece :)

The bushing goes through the pivot hole in the blade. The blade "swings" over the bushing. The washers sit on a collar on either side of the bushing. The handle slabs/liners sit on top of the washers. So, from what I understand this is why you can only tighten the pivot bolts so much. You're just tightening everything down more onto the collars of the bushing. The blade sits "free" inside. Hence, the need for tight tolerances. You would have to fill in the space in between where the blade has tolerance to remove any excess space. It won't "tighten out".

Here's pretty good article with pictures.

OK, I understand now... hmmmm, I would like to alter that somehow... I'm not comfortable with a very smooth blade unless it has a ridiculous detent.

You can alter this but it requires disassembly and material removal, with consequent warranty invalidation. If you want a knife that doesn't open so easily then the Paramilitary 2 is the wrong knife for you. You might want to try one of Spyderco's excellent mid-locks instead.
