All About Pocket Knives

I recently obtained this pocket knife which was a metal detector find in UK wonder if anybody knows anything about it.

At the base of the blade by the handle, is there any lettering stamped in to the blade. You can use a pencil to write back and forth over the rust and see if it removes enough rust to see it. Is it silver or aluminum?

Hi yes it’s aluminium and has no makers on the blade only has patented and a number on each blade.

If you drag your image onto google images (AKA: google lens) you will see a bunch looking very similar, maybe some clues to be found in there.

Thanks I never thought of that.
