I started out buying cheap junker knives like Maxam and S&W. I still have them all, and I still love them for what they are. But I have stopped buying knives that low in quality since my collection of crap is pretty much complete. I then moved onto quality knives in the 30-100 dollar range such as the Spyderco Native, Kershaw Leek, and Buck Nighthawk. Now I am concentrating on higher-end knives such as Mcustas, the Manix, Skirmish, SERE2000, and I just ordered a graphic Sebenza. Next I want a Nakamura, and maybe an Emerson Commander.
However, that doesn't mean I won't buy cheap knives. They just have to be good cheap knives. My Opinel, Mora, and SAKs are some of my favorites and they are all really inexpensive. I plan on buying more. Many more.
You'll find that many knife knuts here that buy high-end knives and customs from 100 bucks to 800 bucks (and beyond?) also have a fondness for good inexpensive knives like Opinel, various Moras and Puukkos, as well as SAKs and inexpensive but quality slipjoints.
You'll also see budget knives like the BM Pika, KA-BAR Dozier, and Buck Mayo Cutback and Hilo get a lot of love here.
I may have a Sebenza on the way, but I still want a Buck Mayo Northshore (around 50 bucks).
Good knives are good knives.
Getting junk knives doesn't give me that "new knife rush" any more, as I have moved on to better knives. But an Opinel still gives me a fix.
Hopefully this analogy won't be too dark... If someone is addicted to a hardcore drug like crack (Sebenza), they can still get off on pot (Spyderco Native). However, coffee (an Mtech POS) won't really give them the high they want.
I am addicted to buying knives. I love the feeling I get when I get a new knife, and that feeling can last days or weeks. The better the knife, the better the feeling. I am now too desensitized to get a high off of a junker. But an Opinel can hold me off for the rest of the week until I get paid
