Bastid's and Paracelsus' posts are both very funny and very true -- but Bastid, what's the story behind your Commandment #5?
Paracelsus, is it only pink mammoth tusk that we're forbidden to use for knife handles? I hope so....
I had a dream in which a gigantic walrus came to me and said ... no, let's not go there.... (If you don't know what oosic is you won't have that dream....)
Collectors usually start out hoarding a large variety of knives, snarfing up anything that catches their eye more or less indiscriminately, and gradually narrow down to one particular kind of knife. I've been going through that lately ... and it can really help control the insatiable urge to buy everything. When I stopped buying knives with a stoopid joint in the middle a few years ago that improved my peace of mind immensely, by eliminating a lot of the inner conflict of wanting knives I can't afford. I still look at folders and admire them but I know I don't want them. Eliminating stainless steel helped a lot too, years earlier.... Of course I still see knives I want and can't afford, but not as many of them.
I think that process is probably necessary; you have to start out collecting a variety of knives before you can discover where your real interest is, and if you rush the process too much you might find you've chosen the wrong specialty -- but it's something to keep in mind ... think about what you really like. Don't settle for knives that have features you like but also have a feature you don't like -- there are plenty of those around. There's no need to bankrupt yourself to buy knives that aren't perfect. Repeat that to yourself like a mantra as you wander around a knife show -- it helps.
One knife that's exactly what you like is worth more than any number of knives that cost less but aren't perfect. Add up how much you spent on knives in the last year and compare that figure to the price of that knife you really want but feel is too expensive.
Using knives is more satisfying than buying them -- even just handling them is more satisfying than buying them. Collecting is not just buying things and putting them away!
When you buy a mediocre knife you feel pleased about it for a while, maybe as long as several days, before you realize it's not as great as you thought.... If you buy a lot of knives like that they add up to pleasure for quite a bit of the time ... but it's an addiction; you always have to keep feeding it. If you buy a really fine knife you'll always feel good about it. A few really fine knives and -- okay, I admit it, you'll still want more -- but you'll feel good about what you have, too, and you won't feel you need more and better knives; you'll only want them -- you'll be happy to buy more when you get a chance and you'll still be happy in between purchases, even if it's a long time between.
