I was in Texas for 3 weeks in May. This was my first trip back in 2.5 years. Consumer prices in the grocery stores and restaurants south of Dallas were so high it made my eyes water. A $50 bill is the new twenty. Even fast food was crazy expensive. A simple Barbeque sandwich at HEB was $9, no fries, no drink, just the sandwich. Prices for electricity, construction costs, insurance on property, taxes on property and rents were all nuts. For the first time, even prices on clothing and other consumers goods at the mall were pretty much as high as here in Germany. The days of cheap jeans are gone. Gasoline for the rental car at around $3 a gallon was still reasonable compared to Germany. Folks told me they were working 7 days a week and barely making ends meet and I believe them.
So now I see why my orders from the USA have dropped off to next to nothing: People do not have any money left over at the end of the month for things like knives they can do without. All the cash goes for food, rent and housing. And health insurance, if they even have any.
Prices here in Germany have also risen substantially, but not as bad as in the USA. One example, a package of 6 English muffins in a German supermarket costs €1.79; at HEB in Texas it was $5.26. English friggin' muffins! I know Whole Foods has been called Whole Paycheck for a long time but I didn't even go in one of those stores.
Look up consumer spending overall in the USA and you'll see it's way down nationwide. The EU is in a similar situation. I can't go into the reasons for that without getting into politics, so I'll say no more.
But yes, I can say that knife sales are way down across the board. If you follow the used market, it is also down.
