Up for your consideration, 2 vintage American made 2 blade jacks, one is Colonial the other is not tang stamped with a makers mark, just a patent number and made in USA. It’s very similar to the colonial, so I’m calling it that. Might be one of those USA brand ones we see all over eBay. Regardless, both are solid, carbon steel blades, mostly full, tight, with half stops and all blades snap. The unbranded one, has amazing snap. I’m tempted to keep it cuz I like it so much, but thought I’d throw it in to sweeten the pot. Both have been carried by me this last summer, but not heavily used.
