Here is my favorite Keen Kutter, their #K911, a SFO Schrade Walden pattern 138L
Bowie Hunter. The blade is faintly etched
"Keen Kutter K911". I don't know what year it was made, but the regular production 138L Schrades date from 1957-1973.
It is a 9 3/4" overall length, a saber ground carbon steel 5 1/8" clip point blade, leather washer handle with spacers, curved aluminum bowie style guard, and aluminum flat pommel. This pattern was a varient of the H-15. It was first cataloged in 1957, two years before the introduction of the H-15. It listed for $3.95 in 1962. 1973 ½ was the last year for this pattern, and it listed for $8.00.
If you are familiar with the regular prouction Schrade Walden knife, you will note the presence of additional red spacers, and fiber spacers which changed the leather washer handle profile. It has the stock Schrade Walden tangstamp, as did many of the SFO knives from those years for Keen Kutter, Sears, etc.
Here it is pictured with the standard 138L.
The pommel is also riveted, not wedged or pinned as was usually used on this pattern.
