So does anyone know what these are?

[IronWing]

Leather punches for machine use?

Still look like soldering tips but w/ the different sizes punches seem more likely. The size differences lead me to reject the dart hypothesis.

 

[sdifox]

looks like old school soldering iron tips to me....

soldering iron tips were never threaded.

 

[IronWing]

Inspect the threads carefully and see if you can figure out if the crud is animal, vegetable, or mineral. Also, can we get a full shot of the hammer headed thing to the far right. How do those things that look like extensions attach to the points or do they not attach at all?

 

[Humpy]

I'd agree with those who say leather punches. If that is a paper plate they are sitting on, they look about the right size. The other pieces without the tips could be a punch extender. Just needs the machine to screw them to.

The spring is in there just to fuck with anyone who found his collection of leather punches.

They probably came from a moccasin factory.

huh, never seen the threaded soldering tips before.

Dart tips??? Have you people never gone to a bar & played darts before??

Dart tips: Doesn't explain the other various extensions, springs and odd shaped ones
Soldering iron tips: Again, the extensions and spring doesn't make sense. Also, they are way too sharp to be for soldering.

I originally thought it was a needle valve needle, but the shape doesn't quite lend its self to that. Those needles usually have handles attached.

They are too long to be traction studs. They would easily break off.

They are too greasy to be meat tenderizers.

I am stumped...
... but I refuse to surrender. Still searching...

I have a set of floor standing speakers with similar looking spikes on them.

Tips for a scriber?

Possible he wore one of these???

I kid because I care...

Playground ball deflaters. Your father-in-law was a very mean old man.

They look like carpet spikes for speakers

This - those look like carpet spikes.

En route to seeking the truth I came upon a tennis racket stringing machine. If it hadn't had a racket painted on the base I never in million years figured out its function.

 

[ManBearPig]

Ask on reddit r/whatisthisthing. Those people are crazy at this stuff.

 

[Humpy]

I did a reverse image search and figured it out.

They are a motorcycle!

I still wasn't sure but I knew I was right when I found this picture of a cobbler's awl with what looks like a similar pointy tip with flat, wrenchable sides on it:

Cobbler's awl was where I ended up as well. I couldn't find a mechanized version though.

Also: Don't image search on leather awl threaded machine unless you're into gruesome injury pics.

Edit: Also: Searching on cobbler punch is an exercise in frustration. TexasHiker has a point about english.

I think so. Their shape pretty much dictates they are intended for puncturing. They are heavy duty so probably for something like layers of leather. That they are threaded and numerous suggests they fit some piece of machinery on an assembly line.

The spring and the other parts may or may not belong to the same machine.

What did he do for money? Due to the quantity, I'd image they went into a machine that automatically made holes in things on a conveyor line. Meat tenderizer maybe?

They were not used in a food industry.

Too long to be speaker spikes. That would cause some serious instability.

They look about as long as the spikes on my Def-Techs

 

[WiseUp216]

Part of a handheld metal etcher? Those also have springs inside.

I've been around manufacturing and machining for 10 years but those don't look familiar to me. A little history of the father-in-law or what they were found with could help identify them.
