Summary: this is a very nice Randall model #18 crutch tip made from a Solingen stainless steel blade.
Condition is excellent with what looks to be only light use and resharpening, both sides of the blade with light scratches from past use / insertion, etc. Small sawteeth up top with a sharpened clip. Etched "Randall Made Solingen" Separate S blade stamp, "STAINLESS" across the ricasso. The brass guard is 3-3/8" end to end, I left the brass uncleaned as the patina looks quite nice. The pinched tube handle is 4-7/8" from the back end to the bottom of the guard – the tang extends 1-7/8" in to the handle. (end of tang to end of hollow tube: 3") The rubber end cap is black and marked with the 20 over 1 stamp, overall length of the knife including the cap is 12-3/4. Cord wrap around the handle is not original, I left it in place as it's tight and well done.
The riveted Johnson roughback sheath is in great shape, I picked a bit of verdigris from around the rivets. I'd refer to this as "excellent / carried", snaps work as they should and there's no issues with the stitching. Carry / handling marks on both sides, a solid gray stone is in the front pouch.
9 photos for review – as shown, a new Randall Knives carry case is included. This is a totally cool knife, a great one to tuck away in your collection. These Crutch Tip's date back to the mid-60's, not sure exactly when these Solingen blades were used but mid to late 60's is a very safe bet. Check it out... thanks and good luck.
