Metal frame knife

[edge213]

Maybe this shouldn't be in the Robeson thread, but I'm posting it here in hopes that Charlie may find it sooner.
This knife has definitely been worked on. It has an Imperial main blade. The secondary blade is unmarked.
Tom Kalcevic calls this handle construction "metal frame handle". I've only seen this type of handle on Robesons.

My question is, did Imperial also use this type of construction or is it a Robeson frame with an Imperial blade.
The blade does fit extremely well.

Happy to help.

I have heard Robeson’s patented technique referred to as “inter-frame”, as well.

The bolsters and the edges of the liners overlapped the edges of the handle material. There were no handle pins, but there would have been a rocker pin in the bottom center for the backsprings.

Imperial had a technique that was kind of similar and it is referred to as “shell handles”.

Shell handles are not solid pieces of material. There is a hollow area between them and the frame.

Robeson’s interframe handles were solid slabs of material.

Bernie Levine devoted sections of two of his WHUT-IZZIT? columns in KnifeWorld Magazine to Robeson’s technique.

I cannot tell you the issue numbers.

Hope that helps.

David, I have one like it marked "PINE KNOT". I had posted it a while back and I'll try to dig up the post. There was some discussion about the brand and whether this one is an original . The blades may be replacements?? Looks like the 30's-40's, a bit inexpensive looking, Delrin or composite inserts and a tabbed on shield. Bolsters appear to be inserts within the outer frame ring. I've seen others made that way, in aluminum if I recall correctly. I put this one in my " " category. Good luck, J.O'.

Just read "Robeson's" answer. The bolsters on this one aren't the "shell" types tabbed onto Colonials and Imperials cheapies. These are solid and pinned through. Still trying to locate that original post. J.O'.

Found that post. Did a "PINE KNOT search on the General Knife forum and found it for Feb.4th, 2021. Wayne had answered it may be a Robeson for PINE KNOT. Others thought it was a mutt. J.O'.

Charlie, the knife that I posted is not "shell handles". It is solid construction with pins through both bolsters.
I am very familiar with "shell handles".

Problem is, I’m not really familiar with Imperial.

The knife in the OP photo looks like that type knife to me.

Sorry.

Robeson’s interframe knives had solid bolsters and handle slabs.

The OP knife is not ringing any Robeson bells for me.

Thank you Charlie, and Merry Christmas.
