...In fact most Seki-made folders of the era have these soft pins, the old aluminium Spyderco Civilian even having one for the main pivot: This is pot metal you can actually mark with your NAIL...: Try all your old Spyderco's 1980s pivots, Endura, Delica etc, their pivot extremity will take a mark from your nail...
This softness means any amount of opening/closing cycles will eat the pin inside and loosen the knife: The current hardened screw pivots are a huge improvement...
Did anybody spine whack back in 88?
Those soft unhardened no-screw pins are actually common on Seki City made folding knives, especially older ones, and even some of the high end ones: All the early 1980/early 90s plastic handle Spydercos are made like that... My Aluminium Spyderco Civilian had a soft pin for the main pivot, and it was an expensive knife back in the mid 90s... The pin's metal is so soft you can mark it with your nail... On the polished micarta handle SERE they would have to be hardened pins to take the fine polish, so the micarta pins are definitely harder: No nail marking is possible on mine...).
Even the very first Spyderco Military had screws that were just drilled directly into the friable G-10 scale on the opposite end...: The screw thread did not touch any metal, they just screwed into soft synthetic on the other side... That was what was holding this thing together... That is even far worse than soft pot-metal pins... It is actually unbelievable, but fortunately it didn't last long...
Sure your 20 year old Seki folders are holding together fine, and so did my Civilian for 15 years, but really, there should be no place on a serious knife for such garbage soft pot-metal pins... It's just common sense...
Also there is no reason for the pin diameter to be smaller on the synthetic handle version than on the micarta...
I've seen $20 folders that had proper hardened screws everywhere... I think even some $10 folders have them... People who are defending what Seki City did for decades are just in denial: Sure, these older expensive knives are holding together, if without any serious test, but is that how they should be built when today even gas-station junk has proper screw pivots? Of course not.

Destruction testing such a knife is a very academic thing to do, since they can't be bought new now. It doesn't answer the practical question " is knife A tough enough for me?"
I can see some value in putting a few current production knives through some tough, comparable tests, to see which excel. But doing that to a vintage knife has no practical explanation.
