Exposed nut still comes on an all leather handle. It is no longer doable on any other handle. Hope this clears it up. I didn't mean to give anyone pause, just showing a very "way-cool" knife as is evident by the option list..."&"...the great stag.

Absolutely way cool!
Thanks for the info, Cap. This place is great to learn about Randall’s.

I learn something new every day.
I did not know you could get an exposed nut on a non-leather handle.
Thanks again, Capt.

Subject to confirmation--

The exposed nut on the leather handles would allow it to be tightened to compensate for any shrinking of the leather washers.

But I suspect that is rare, maybe does not happen?

Here a few Model 5's, non leather, with a nut on end of the handle. Only one knife, with stag has an acorn. The other stag handled knife has a ? in the butt of the handle.

Not really an acorn nut!! But some nice engraving on the hilt.

Here's Rod "other" photo which was too large...
Stay Sharp, Ho-Ho!

I just shot a few pics of this classic & posted a couple in the "Knives of the Week" topic. Acorn nut? Positively!
Stay Sharp, Capt. Chris

Good grief! Y’all keep on posting some classics for sure.
