I can’t produce any pairs, but I can think of a few possibilities. S&W, but I have yet to come across a Smith and Wesson knife I would care to own. I have neither an HK pistol nor one of the HK Benchmades. No Mauser to go with my branded Victorinox GAK. No Berettas.
No Browning guns to go with a branded knife, although some people have mistaken my FEG P9R for a Hi Power. I have paired the FEG with any one of a number of puukkos. There is a tenuous linguistic connection there: Finnish and Hungarian both belong to the Finno-Ugrian language group.
Even if I owned a Glock, I don’t have the knife to go with it. It would almost, but not quite, be worth it to buy one just so I could pair it with a Golok. However, I would be happy to own a 1911, which could pair up with one of my Colt slip joints.
