Nah. Glock began selling firearms 38 years ago. Averaged over those 38 years, they sell nearly 300K firearms/year, possibly more based on European sales. That's 11.4M handguns. I suspect the average Glock owner/user has owned/used 2 or more Glocks, so about 5.7 people have owned/used Glocks. Of those 5.7M, let's say half have passed away ovr the past 38 years. Of the remaining, at least 10% (a very conservative number) are Glock fanatics who would likely already own the Glock field knives and would jump at the chance to buy an inexpensive/high quality Glock Bowie. That's 285K people.
So yeah, they'd sell "tens of thousands" of them at $59.99 if they were high quality and a superb design. Done deal. Once word got out that such a superb knife was available for such an inexpensive price, people who did not know Glock due to their firearms, would begin buying them.
