What do these three knives have in common?

 

[oilburner]

I would like to have any one of them in my pocket?

 

[Railsplitter]

Is this a trick question?

 

[GRIM 62]

They are all GEC Conducters.

 

[supratentorial]

They're all swell center pen knives. It looks like the top one has an old Queen stamp and possibly three blades on a split backspring. A whittler is a type of pen knife so I'll stick with my first answer. Nice knives! :thumbup: The one in the middle is especially impressive. Is that the ivory Conductor?

 

[Railsplitter]

Good eye, Jake. :thumbup: I thought they were all GEC Conductors too.

 

[Invoice]

No, not a trick question. Just having some Sunday morning fun. Yes they are all Conductors. Top one is a Queen split spring. Good catch Jake without seeing the springs. Middle is an ivory.
They all have something else in common.

All designed by the same person, name i've forgotten, but he moved over to GEC from Queen.

That could be. Still looking for the right answer.

 

[johnny twoshoes]

They are all made in Titusville Pa. :thumbup:

 

[Invoice]

Yup, but there is more.

 

[johnny twoshoes]

You own them?
They all have 1095 carbon blades?

:indecisiveness:

 

[Invoice]

I would say so. This is fun do you need a clue?

 

[denniskelley]

Unused all from the Civil War Era!

 

[russianpolander]

I got it! You are going to do a giveaway on all three!

 

[johnny twoshoes]

Natural scale material.
Three pins in the scales.

 

[Invoice]

Nope to all answers except the three pins.

 

[thatotherguy]

Ummm, I got nothin.
