Are Pythons now extinct?

[Bill PhinnParticipant @billphinn90025]

I did try to find more info about the patent, Michael, but without success.

 

Anyway, in the name of science I sacrificed a perfectly functional Python no.2.

If anyone can explain the physics behind the spring in the handle, I’d be fascinated to hear it.

Very gallant of you, Sir !

Let me have first-stab at the Physics

Inserting the File-tang in the normal way will expand and distort the spring to some extent, and will embed it into the wood … at the same time, the spring will grip tightly onto the corners of the tang.

With such a short spring I would have thought wobble was likely as you are only gripping a short length of the tang

Nice find, Paul 

… just a little late to save Bill’s specimen

On Bill Phinn Said:

Dave, I can’t actually picture what the manufacturers meant when they said the Pythons have a “hidden spring inside the handle”. I’d always assumed it meant the ferrule has some sort of internal spring-steel prongs that embed themselves in the wood around the hole. I suppose there’s only one way to find out and that’s to chuck a Python in a fire and see what’s left behind after an hour or two; a reckless act, perhaps, given we now know the Python is an endangered species.

 

Bill, can you update us on what turns up when your order arrives, i.e. real no.3 Pythons or substitutes? Thanks.

Yes, The No.3s in the parcel are genuine Python brand.
Just had a look at the link again, they may now also be out of stock.
The other “normal” handles in the order were not Python, which is only to be expected, as no such claim was made.
Delivery was prompt, just the minimum postage price would make them quite expensive, if you only ordered a couple of file handles

Can’t say I recall ever having much trouble with my standard wooden file handles coming off in use or giving other trouble. They are older ones bought at a garage sale but seem to be as new. Not sure if today’s equivalents are as good?

In the days of yore, at work we always had cast aluminium file handles with distinctive grip recesses in them but haven’t seen any for years. My own disappeared when a visiting relative was keen on recycling aluminium “scrap” for cigarette money. I still haven’t forgiven her.
