Hi I posted this in general but thought I would ask the experts here. I just sharpened up an old wildcat ridge 3140 for the groundskeeper in Costa Rica. It's seen a lot of use. It's stamped Japan. Also engraved as 19031 of 30000. Engraving is poor.
I was curious if anyone knows when these knives were first produced.
Thx for any info. Apologies if this is cross posting.
