Manix construction question (other spydies too)

who said thicker? just a different material. pb washers are self lubricating and stronger and wont deform. i have had nylon washers deform.

Yeah, but the thinner the washer, the less room it has to deform. There must be a reason they still use nylon. Has anyone asked this question directly to spyderco? Maybe since the space is so thin, a bronze washer would be impractical to make?

BTW, FRN is fine by me, but I work in an office most of the time. G10 is good for heavier use, but I like the price of FRN. I'd take a better steel over a better handle material anyday.

I have stripped the phil heads on my CalypsoJr, it does suck. A little loctite and tightening them with a vice grips does the trick. Torx would be much easier!
 
I've had nylon washers to compress and some to actually tear on me. Of course I like a really TIGHT pivot!

You said so yourself, you said you found it difficult to make them as thin as the Spyderco nylon washers, which implies that other knifes use thicker washers. Again, how do you know that you compressed a washer as thin as those from Spyderco. And how do you know you did not compress the PB washers. Did you measure the thickness before and after? Or while in the knife? Nylon btw. is self lubricating as well. Again, I fail to see how you would tear the washer either by tightening the pivot or during use, as long as you have been careful not to get contamination underneath the washer during assembly? Neither during tightening nor during use should substantial forces act tangentially to washer ring.

I would hope a real company could make thin washers better than i can in my garage :) I dont really have the right tool ya know?

Funny how a baby boa with tiny little washer or a CRKT Snaplock have PB washers along with BM now and CRK for a long time. I don't think a more expensive material is used on a whim.

Go back in the posts a few years and find folks defending 154cm in the BM land or VG10 in spydie land when people were asking for s30V. Some people dont like change.

I just know what I like in knife materials. Any nylon does compress easier than PB (metal) and does tear. And I really don't think nylon is self-lubricating - never heard that one before. I have always had to use addtional lubricant. Teflon washers are. PB is. But nylon? Maybe I'm wrong but I still want PB washers.
 
We've been experimenting with both pb washers and thicker Capton washers.

Most of the Seki made stainless models have already converted to pb washers.

Currently Golden is moving to thicker Captons.

It is possible to deform a Capton washer, though not easily. they will go back to shape easily as well. Pb washers can also be deformed, but they do not go back to original shape.

The deeper one looks into solutions, the more things there are to consider.

In our CQI efforts, all solutions are considered. Cost is rarely a factor. Performance and safety are always first. If cost was a factor, you wouldn't see so much in the way of very expensive steels on most of our models.

I think Spyderco makes more models in VG-10 and CPM-S30V than other makers.

thanks for the reply sal. any way to find out what models use what type of construction?
 
I cant see PB being so much more expensive that it wouldnt be considered, what would 100 washers of that size cost? 50c?

Besides, if the pivot is torqued correctly nothing is going to get in anyway. I have a brand new Para-mil, Military and Manix on the desk in front of me and I cant see any real way for something that would be big enough to cause a problem to get in.

If it did get full of cak, just blast it with brake cleaner then apply some tuf-glide.
I would also like to see someone use a Manix to the point where there would be blade play (assuming it wasnt abused by prying)

I'm not a SpydieHolic but they are growing on me more and more. I had a little Jesse Horn lightweight that a pal gave me one Christmas. Well, I beat the hell out of it, left if full of squid juice from Sea fishing in Australia for 3 months. used it to saw through sheetrock and God only knows what other stuff that would give Sal nighmares. When I finally got around to cleaning it, I dropped it in a cup full of dish soap and boiling water, scrubbed it with a car tyre cleaning brush and oiled it. Good as new. If you look at a Nylon using Para, Mili or Manix there is no way you are going spit and cuss because the Nylon washer let you down.
 
there was another post where Sal said trhat the paramilitary has moved to PB - there has to be a reason. I assume they wouldnt do it on a whim. For a hard-use knife - all metal is a good thing IMO.
