Sounds like you got a couple bad ones. Maybe that's why the knives were being sold.
ALL of the problems that you mentioned are problems that I've also experienced with
EVERY manufacturer (even companies that have been around for less than 10 years) though by far the most problems have been from knives by Queen. It's old news. The complaint threads used to be a common occurrence. I've heard the old tooling excuse used a lot. I'm not sure if I buy it. Maybe.
I'm not always sure if I'm on the same page with other collectors these days. A lot of folks seem to care about completely different aspects of knives. And some things are a matter of degree. A few pinholes of light through the springs will have no real significance. But a larger gap and poorly fitted knife with wobbly blades and liners that buckle obviously isn't good craftsmanship. ...Yes, I've gotten ones that bad!!
They weren't the black box knives though.
The "black box" knives were a mini renaissance in their time. Some are 25+ years old now. I've owned at least a couple dozen of them and in general, they've been very good. They're generally the best knives that I have ever gotten from Queen. And the quality can be comparable to knives that cost much more. The patterns were terrific. The grinds were good (MUCH better than the grinds on many of the Schatt and Morgan knives). And the jigged bone on Queen's knives made most of the stuff from other companies look amateur... but lately their jigged bone has been much less impressive and other companies have stepped up their games. GEC went from store bought jigged bone to amateur to best around.
At the prices the "black box" knives go for now (hidden among tons of foreign made Winchester branded knives on the big auction site), they are sometimes extremely undervalued. I still carry a couple and have some in storage for a rainy day.
Anywho.... I'm sorry that the knives weren't better examples. You might contact Queen and see if they'll fix them up for you. Or maybe just return them to the seller.
