Condition

I would grade this particular knife Fair to Good Vintage Pre-Owned Condition.

Both blades show substantial evidence of previous use, including scratches, sharpening marks, dark spotting, oxidation and age-related patina. The main clip-point blade has experienced noticeable sharpening and use but retains its basic profile and an intact point. The smaller pen blade exhibits similar scratches, spotting and sharpening wear.

The yellow handle scales appear complete without an obvious major crack or missing section. They do show age, discoloration, scratches and handling marks. The oval shield remains in place.

The bolsters, backsprings, liners and exposed metal components show scratches, tarnish, oxidation and patina consistent with an approximately 65-year-old working pocket knife.
