Well I guess my opinions are influenced by my experiences, which is something that probably applies to us all. But I thought I'd take a bit of time to clarify my position. I've seen or read reports of quality knives that fall around the $40-$50 range. I think the prices Phil gave were a little too extreme. There's a large scale of quality/flair. I've wound up paying from about $25 to $170 on a knife. With the exception of my first purchase, a Smith & Wesson SWAT knife (not as high quality as my others but it can get the job done. I just won't buy anything else from that line due to their dishonest business practices. And I'll only use the knife for something that could put some serious damage on the knife that I wouldn't want to subject my others ones to while making damn sure my fingers are safe.) the lower priced purchases have all been Spydercos. Positive experiences with them and knowing that they have good quality control and customer support mean that I'm more comfortable ordering stuff from them compared to other companies since I know that their lower priced models will be able to do the job well. While there will be some $20 knives that are good, there will be many that are bad. Just like I know there are some bad higher end knives out there. The campanies that I've learned to trust don't make most of their things in the $20 range so I'd rather have 1 $200 knife from a company I've grown to feel secure in.
Oh, and I think most of the world gets by with SAKs which vary in price. Hmm . . . that would be something interesting to find out some day, which SAK models have been the most successful. But that's another can of worms and a subject for another thread.
