Summary: this is a rare "All Stainless" model 18 made in the 1980's. This knife has a 5-5/8" stainless steel blade with sawteeth, large stainless steel guard, knurled stainless steel handle, and a knurled stainless steel butt cap. The knife is in excellent+++ or better condition, no signs of use with just a few light handling / wipe marks that can only be seen if the knife is turned in direct light.
The knife is paired to the original Johnson roughback sheath that has a plain salmon stone in the front pouch. Condition of the sheath is also in excellent+++ or better, you'll find nothing but a few light handling marks front and back.
8 photos for review – as shown, a new black canvas carry case is included. Very few of these all stainless 18's were produced (it's said less than 100 total and many weren't knurled), only about 25 of these were made with the 5-1/2" blades. All said, it's a very collectible knife perfect for investment purposes, these "all stainless" models are very hard to find and seldom come up for sale. Thanks and good luck.
